computer help please

looking to buy a new PC soon (within days) .

below are the specs i'm reviewing.


PROCESSOR Intel® Core™ i7-940 (2.93GHz, 8MB cache) "I belieave that is a quad Core?"
OPERATING SYSTEM Genuine Windows Vista® Ultimate (English) Service Pack 1 64-bit
MEMORY 6GB Tri-Channel DDR3 at 1066MHZ (3x2GB DIMM)
VIDEO CARD SLi, Dual nVidia GeForce GTX280 1024MB
HARD DRIVE 500GB - SATA-II, 3GB/S, 7200RPM, 16MB Cache
SOUND CARD Integrated 7.1 Channel Audio
COOLING OPTION Copper base Heat Sink with aluminum fins

Currently priced around $3,200.

I use zbrush and XSI heavily therfore I am looking to push maximum visuals with minimal "slow down".

Am I on the right path? Any suggestions?

    sounds powerful and expensive but I guess those 2 go hand in hand.

    what motherboard? case? what about a 500GB sata2 drive with 32mb cache instead of 16mb? they arent much more expensive but Im not sure the 32mb makes much difference to 16mb?

    That's just about what my Sager NP9262 has. I have no problem at all.

    Anyone correct me if I'm wrong but I believe the benchmarks on SLI 9800's weren't anything to rush to the store over. I don't think the extra arm and leg is worth the dule performance cards anyways (more like bragging rights that mean nothing in the end). I would get the machine you have in mind and get only one 9800 for now... If you think you absolutely need the other then you can always get it later an upgrade.

    Hope this helps...

    i7 is a quadcore with hyperthreading cpu... so basically it shows up as an 8 core cpu.

    You can skip the dual 9800GTs and go for a single GTX 280 or 295 card... I think that's a whole lot more power than 2 9800s... the new line of NVIDIA cards are dual core GPUs, meaning they have 2 video processors on 1 card.

    I have a 1 gb 9800 gt... I'm thinking I should have just threw in another 100-150 to get a gtx260.

    It would help even more if you listed what manufacturer/brand of the actual parts and their cost. Some brands are known to cause issues with other brands. Also, what power supply are you planning to use?


    edit...


    is there a reason why you want to go with such an expensive cpu? the 940 is pretty much double the price of the 920... are you going to get double the performance?

    The i7 920 will be a blazingly fast cpu, why would you need to spend so much more for a marginal increase? For the 250-300$ you can save by going with the 920, you can put it into a faster video card and a 2nd hard drive for faster swap space.

    The rumor is that the i7 will be getting a die shrink later this year, and prices will come down... so in 6 months, your 600$ 940 will probably be worth 300 bucks when faster/more efficient i7s hit the market.

    A computer is like a car... it's a constantly depreciating asset... buy the best ratio of performance to price until it needs an upgrade.

    ew dell... build one for cheaper.


    a single gtx280 will probably be more than enough for anything anyone around here can throw at it in terms of 3d work.

    It's a gaming 3d card... not a 3d workstation card.

    perhaps you should start reading up before you just start buying systems or parts. Just because you are picking out the most expensive bits and pieces doesn't mean it will automatically be the best for you.

    The worst thing you can do right now is start throwing money at a system like this.

    What else comes with this system? what monitor and size, keyboard, mouse, etc... list everything.

    cause I'm well under 2k right now with a similar system built from parts from newegg.com :D

    I haven't used zbrush or xsi yet, but I can tell you my quad core 9300 has yet to start chugging at anything I've thrown at it in max. That i7 configuration is probably faster than my system by another 30-40%... and my system probably would have cost around 900 to build if I were in the US.
  • Ephesians 2:8-9
    Oh trust me, i know your right.
    I petty much know dell is rapping me in price. However, for me, from a personal stand point, i cannot stand putting my own pc together. My current PC was put together and it barely runs now. The process of Software initialization alone was horrible (bios set up and such). What's worse is i know its my fault or non understanding. However all that aside, at the moment i simply have zero time to even put one together because of a hectic work schedule. Thus my willingness to pay alittle extra for a more reliable assembled machine that was not put together by a monkey (me). Not to mention the piece of mind. I'm going through dell because my work machine is dell and has yet to fail me. :)

    Oh thank you, yoru right,.....it borught my pc down about 300bucks. Thanks. :)

    What's most important toi me is the ability to work efficiently, with little to no slow down, on my 3d stuff at home.

    To further discuss vid cards, which is better then for the purposes above?

    SLi, Dual nVidia GeForce GTX280 1024MB

    or

    nVidia GeForce GTX280 1024MB

    or

    one single nVidia GeForce 9800GT 512MB

    pay a little extra? lol... 3200 for that system is preposterous, but hey it's your money.

    btw, what do you need vista ultimate for? Most users won't even need the extra options in ultimate...

    Even with your i7 940, I have priced a similar system from newegg without such a fancy automotive painted case for 1900$

    A few looks around the web... like the EVGA board can tell you what to match up in terms of parts, and they'll be known to work. My system works fine because I put an evga motherboard with an evga video card, corsair powersupply and corsair ram. the 1900$ selection of parts I came up with are not cheap parts, they all have either lifetime warranty or extended warranty from factory.

    Hell with the money left over from building the system you can buy a cintiq.

    with the gtx 280, vista is a better choice, unless you want to wait for windows7 later this year.

    xp will not support directx10, though with non realtime rendering, xsi might not even use dx10. not sure about zbrush... you might want to look into it.

    bleh... 1 hour tops to put the rig together... and that's if you're dirt slow and you're clumsy. From there it's another hour to install the os. Is your time that valuable?
  • Ephesians 2:8-9
    ok i think then i'll go with vista but, out of the 3 vid card set ups i menioned, which one do you recomend i use?

    ok so based on the comments here are the specs as of now.

    Intel® Core™ i7-920 (2.66GHz, 8MB cache)
    Genuine Windows Vista® Home Premium (English) Service Pack 1 64-bit (i'm hoping my XSI and zbrush will run under 64bit system)

    MEMORY 6GB Tri-Channel DDR3 at 1066MHZ (3x2GB DIMM)
    VIDEO CARD SLi, Dual nVidia GeForce GTX280 1024MB - is this good for a 3d work station?
    1.5TB Performance RAID 0 (2 x 750GB SATA-II, 7200 RPM HDDs)
    SOUND CARD Integrated 7.1 Channel Audio
    COOLING OPTION Copper base Heat Sink with aluminum fins

    Priced at about $2,700
  • EarthQuake
    I've never understood the want to spend upwards of $3000 on a computer, if you pay $1000, or $3000, whatever you buy will be obsolete, and out performed my a mid-range $1000 computer in 2-3 years. So whats the point of spending that much money? Honestly, unless you need to work on like 100 million polygon models, you're not going to see a huge difference in performance buying a $3000 computer over a $1000 computer. It just makes no sense, there is a price curve, and you pay wayyyy wayyyyy more for slightly better, the new and more fancy it is, the less value it actually has.
  • Ephesians 2:8-9
    well right now the video card is creating a price difference of about 1000 bucks. I just want the card or set up that will allow me to push at least several million polys. gt9800 512 or gtx280 1024.

    Am i better off going SLi for either one or just a single option?

    SLI GTX280? isn't it overkill considering a single 1 can handle resolutions up to 2560*1600 and still maintain 32fps with AA4X + AF turned on? If you need those stats, get a 9800GX2 i'm pretty sure it'll be way cheaper than a GTX280 and beefier than a GTX9800.

    http://www.tomshardware.com/reviews/nvidia-gtx-280,1953-29.html

    If you wanted a workstation card then you would have picked a quadro (which absolutely sucks for games).

    You should go with 8GB of ram, and last time i checked, the DDR3 performance wasnt worth it considering the price (lower DDR3 might be dirt cheap now?). Some boards support both DDR3 and DDR2 that means a maximum of 4GB tho so watch out for that. Spend money on the CPU first then a GOOD motherboard and pick a kickass power supply. RAM is pretty much the same thing, one will argue that ram timings is still better than higher clock but that is not always true depending on the task performed.

    RAID setup? you do know that adding a 2nd hard drive into the chain doubles your risk of data loss?...unless it's RAID-5...in which case you need 3 disks.

    -RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and full capacity, but all data on all disks will be lost if any one disk fails.

    -RAID 5 (striped disks with parity) combines three or more disks in a way that protects data against loss of any one disk; the storage capacity of the array is reduced by one disk.

    So yeah just my thoughts :)

    I think the dual 280 cards is overkill too.

    I have about the same system except I have a single card and 2TB of HDD space instead.

    Also I got my system a lot cheaper. I'm pretty sure there are plenty of sites that charge less for building your computer.

    Im not really an expert on this, but arnt you supposed to use an amount of RAM that is evenly divisible by the number of cores in your CPU? ex: for a quad core use 4, 8, 12, or 16 Gigs depending on what your Mobo and OS can handle?

    I really cant imagine having trouble pushing a couple million polys with this beast. I just put together my own desktop on a total budget of around 400$ and it can push two million polys in my main modeling app without breaking a sweat.

    guys, core i7 is tri-channel ddr3, not dual channel for quadcore or dualcore, meaning it comes in sets of 3 not 2, so he will need to get matched sets of 3x1, 3x2, or 3x4, gigs of ram, it's 3,6 or 12, there's no way he can put 8 there.

    6 gb of ram on that system should be stupid fast, i7 is brand new archietecture that has no front side bus and must use ddr3.

    http://techreport.com/articles.x/15816


    yse 2 gtx 280s is absolute overkill... that's basically quad SLI since a single 280 has 2 processors on it. There is not a single game on the market that will need this.

    I doubt even any workstation applications would use this kind of power, the only thing anyone would want to SLI 2 GTX 2xx cards is to say they have a bigger dick than someone else, since there's no use for it.

    I'm with EQ on this one .... I spent less than a grand on my machine and it's still better than what they give me at work. If you're smart about it you can make a machine that's more than sufficient for a 1000. The latest and greats parts are likely to give you more pain than pleasure since they're not proven and refined yet anyway.

The latest and greats parts are likely to give you more pain than pleasure since they're not proven and refined yet anyway.

    Right, i built a system with a q6600 quad core, 8 gigs of dd2, and a pretty standard($120) 8800. This is a mad fast system, and it can easily handle 32 million polys in mudbox2. Total cost of the system was around $1100. 2 280's is just..... crazy overkill, a decent 8800/9800 will give you all the performance you actually need, with the CPU/Ram that you will have. Actually, with the cpu/ram you have your bottleneck is going to be your hard disks, when dealing huge files the biggest problem you will have is reading/saving them to disk.

    Honestly i would just set a budget of about $1500-2000(if you want the latest CPU etc), get the best you can for that price range, and you i know you will way more than happy with it. But really be careful buying top of the line cpus, you often pay 2 or 3 times more, for a very marginal performance increase 10-15% for 2/3 times more? No thanks.

    For example
    i7-940 is $560
    i7-920 is $290

    Both of these CPUs are very good, quad core cpus, but one is 1.9x more expensive.

    Now lets look at a benchmark here:
    http://www.techspot.com/review/124-intel-core-i7-920-940-965/page5.html

    The twice as expensive cpu gives a very small performance increase, to the tune of a couple % REALLY not worth it for any reason.

    Even the 965 which runs about $1000, or 3.4x more epensive than the 920, is at best 20-30% better performance.

    You gotta look at the price curve of this stuff, high end stuff is never worth it, this sort of shit is marketed to retards who just want to brag about how much money then spend.

    I recently bought a gtx285 for a system i builded in the past october, and the whole gig does not surpass the 1000 euro. You don't need to waste too much money in a computer, they became obsolete very fast.

    This is less than 1000 euro in spain with a top videogame card, and installing some expensive components to do overclock. I have an stable processor at 3,8ghz.

    • x2 HD Seagate 640GB Barracuda 7200.11
    • DVD/R LG H20N
    • PSU Corsair HX620
    I builded the system in 2 hours and i saved a lot of money buying the gig piece by piece in different stores.

    Prices in USA are far cheaper than in Europe, you could easily build a great computer for less than me.

    To build a computer is more easy than building a lego XDDD

    I own a pair of workstations (dual xeons + quadros), and i'm really surprised with the perfomance of the machine i builded only for gaming and modo. The unique difference i find are rendering times, and the perfomance in programs like Max (the gtx285 is a shit compared with quadro in wireframe views and edition).

    SLI is mainly for hardcore gaming and to waste a lot of watts. I don't recommend it to do 3d, your electricity bill would grow ^^

    With core i7, 6 or 12 gb ram. DDR3 is quite expensive, so 6 gb would be the recommended, you will have enough to work very well with Zbrush.

    Try to make a configuration piece by piece, and look how much money you can save. Dell has become a very expensive brand, and imho, it's better to mount a good mobo instead a dell one (made in china). I have ran problems with dell due to its bad components, with one psu and with one quadro (not pny, dell made in china).

    hope this helps. The more money you save, the better :D

    SLI is totally nuts, and only for people who need to have a big e-penis. Or for researchers who do much more number crunching tasks.

    if you take a good look at stats on cards e.g stuff like

    http://techreport.com/articles.x/16504/10

    you will see that the latest cards only make a difference in "artificial" load, ie the insane resolutions and insane AA settings in shader intenstive games noone will run stuff at. Not to mention the insane noise and power consumption caused by top cards. And power means heat in the system, means more fans, ... it just isnt worth it imo.

    Get something that is fabricated in 55nm which means you get a decent per-watt performance.. or pick a older generation, but within the generation also the "smallest chip"

    rendering a single model is much easier for cards, vs the complex setup in shader intensive games with lots of variations, many meshes... Hence you can push millions of triangles even on old cards.

    buying the latest is just stupid for the reasons mentioned (it loses value too quickly. and one hardly can make use of all the performance, but you pay the "power" even when idle)
  • EarthQuake
    Also, build it yourself too, you'll pay out the ass for dell. Or at the very least price out the parts that you would buy on newegg.com to see how much of a difference it will be, and see if its worth it. If you can't troubleshoot your own pc, buying something from dell may be worth it, otherwise i would go with newegg, just make sure to do a lot of research, and get parts that will be compatable.

    i, too, am hideously lazy and rubbish when it comes to any sort of DIY, and will happily pay someone to do it for me just for an easy life

    i'm also looking for a similarly specced system that i can order online, and had a look at Dell, and also Alienware. The prices are crazy, especially compared to someone like pcspecialist.co.uk ... in fact looking on that site, i've upped my spec to something ridiculous i'll never use, including 22" monitor, and it's still coming in at something like £500-600 cheaper than alienware without display

    edit, i clicked the wrong thing on the alienware. Call that £800 more with no monitor! What the hell do you pay for here?

    Eye opening to say the least from all yalls advise. I think every one of you very much for your help, generiousity in lending advise.

    I'm abit on the fence related to buying through dell now but there are the revised computer specs i've decided to go with now. Any furuther advise is greatly apreciated.

    Still on the fence between these 2 becuase i use a gt8800 at work and so far so good. But hen again the gtx280 (according to that link) seems to outperform the 9800. but then again thats only in games. I want a vid card to do well in both 3d modeling and gaming.

    Thoughts?
  • EarthQuake
    Yeah a 10k RPM drive will definately be good for performance(loading programs, loading/saving files).

    As far as the video card, i think you will see pretty similar performance in 3d work, and either of those cards will be good gaming. I wouldn't buy a high-end 3d card from some place like dell, because you'll probabbly pay more for it than its worth, it might be worth considering buying the WORST POSSIBLE 3d card dell will sell you with your pc, and buying a better one on newegg(changing a 3d card is really easy).

    You can get a GTX280 on newegg for around $325, so if its adding more than that to your final price, i would buy it yourself. I wish they would sell you one with NO video card. =)

    A 9800 GT will run you as little as $130 on newegg. For that price, the value is REALLY GREAT. Again paying 2.5x for the GTX 280 on newegg, and probabbly paying dell $500 for it, or 3.8x! For another fractional performance increase.

    Really, at the end of the day that quad core CPU, and DDR3 ram is going to be EXTREMELY FAST even if you were running a voodoo2 as your video card =D Oh, also 6 gigs of DDR3 will run you about $190 at newegg, so if you're paying dell $500 for it, you're throwing money away.

    3 questions you should answer before dropping the coin on the computer:

    1) Are the programs I use going to make use of SLi and if so what is the gain over a single card?

    My answer) I can tell you from personal experience that SLi doesn't make much of a difference with Maya, 3dsmax, Silo, Mudbox, Zbrush or Photoshop. Any detectable difference came in the form of benchmarks designed to spot the differance. Durring day to day use it wasn't any different. BUT with SLi enabled I was forced to only use one monitor. I don't know if they have changed that or not, but when I tried it out, I found it VERY limiting. The only way I found to run two monitors, was to turn off SLi...



    2) 3k every 2 years to get a new system, or 1k every 2 years for upgrades?

    My Answer) Putting your system together yourself can be scary. But its a lot cheaper and easier to upgrade. Is it really that scary that you want to spend 2x as much and have it be less upgradeable? Also parts manufactures are getting used to people putting their own systems together, many come with big fold out maps and lots of quick start guides that anyone could follow. Most even make the manuals and quick start guides available online in case you ever loose the paper version.



    3) Proprietary software/hardware. Am I reliant on Dell to provide updates or can I get them myself through the normal channels?

    My Answer) In order to maximize profits dell gets cheap deals on parts. Often asking manufactures to cut corners or shave out features. Then they pass you a bill for 2x, sit back and have a good laugh because now it often means you end up relaying on Dell for update drivers. The reviews and things you see online for the latest Nvidia cards aren't going to include the latest Dell deals, you can count on the same card coming from Dell to probably under preform at 2x the price.


    In closing if you're set on buying a system out of the box, the one you choose is pretty good, might be a bit of overkill and you probably won't push the boundaries, even if you paired it down a bit. But I have to agree with everyone else. you can make a better rig, in less time with less cash and get exactly what you want/need without having to comprise. Good luck with whatever you decide to do, I think you'll be fine either way.
