Not sure what it's like everywhere else but In the UK most base level third party 3080 boards start at £50+ over RRP with the OC boards starting at about £800 and going up to almost £1k. We can't get founders edition cards here at all so. They don't count.Assuming AMDs offerings roughly match RRP they'll be at a decent advantage price wise so I'd expect them to do rather well in the consumer space over the next year or so
The shop I just went to had a 3080 box sitting on display in the window.However, a look at the price lists revealed no 3xxx GPUs on offer at all. Best you could have gotten there was the 2070. Such a tease! Anyway, I was there because my 2080 Ti seems to have shortened the lifespan of my somewhat aging power supply. Considering it is now basically a totally eco friendly low power card compared to the new generation it would seem advisable to factor in a decent new one to go with your shiny new electricity-guzzling unobtainable GPU.
Over-speccing your PSU is generally prudent - particularly if you tend to run machines for a long time. With a highish end CPU and a 3080/90 you're looking at maybe 500 watts just to keep the lights on - to me that says get a posh 1kw PSU
Please note if you plan to buy AMD 6000 series, substance is currently only supported with Nvidia RTX. I have asked this in Allegorithmic forums - https://forum.substance3d.com/index.php?topic=35587.new#new
Only raytracing will not work? Just using the program SD/SP will just work with AMD 6800, correct?
I'm not really sure I understand why though... AMD has said their new cards just use the DX12 raytracing API, nothing else, nothing special. So saying their cards aren't supported is saying DX12 isn't supported?Or am I missing something?
Yeah the 3060 TI is almost as good as the 3070, really not sacrificing much.

It's also possible to undervolt your GPU to save a lot of power usage/heat with a more mild impact on performance
I'm planning on undervolting a 3080, on a 650 watt PSU and don't want to upgrade it yet.
A 4K texture (meaning 4096 * 4096 pixels using 32bit color and 4 channels) uses 64MB of VRAM. So assuming there was absolutely nothing else using VRAM, you could have up to 160 layers at 4K resolution in memory before going over 10GB. In reality though you'll obviously never have 100% of your vram free, as the system/apps can be using it for many things, so it's safer to say you'll actually only be able to get between half (80) to 3/4 (120) that many 4K layer into VRAM before running out.
If you're curious, the basic math for getting texture memory usage in bytes is: (x * y * bitdepth) / 8192
Also, I believe Substance Painter only keeps the active Texture Sets texels in vram and uses a baked/merged/flattened map for the inactive ones being displayed. So as long as you don't go overboard on the number of layers per-set, or have a crazy number of sets, 10GB should be fine for most people working in SP.
If you move the working layer to the top its a lot faster than working in the middle on the stack.
Its also getting slower if you use hte passthrough blending mode a lot. Specially on large groups.
Sorry for the misleading information. Still beware of cheap PSUs.
Wrt memory and performance -
We've done comparative runs based on our general designer workflow and they seem to suggest that memory capacity doesn't make much difference.
On our tests between a 2080 and a 2080ti there was no tangible difference (single digit percentages)
We suspect there was a bottleneck elsewhere in the system that prevented the faster bits of the Ti doing their stuff but it did demonstrate that on an otherwise equal system the extra memory didn't do anything much.
In contrast When comparing 1070 Vs 1080 there's a big difference in both painter and designer - practically speaking it means the difference between being able to work at 2k Vs 4k resolution.
My theory is that it's down to having a 50% wider memory bus on the 1080 - which is why I don't think the 3080 is going to be at a real disadvantage compared to the AMD cards in painter and designer
Or am I missing something?
DXR is analogous to Optix, so if apps or games only offer RTX specific hardware acceleration features, it's likely that they are using Optix. Since AMD has only had cards with ray-tracing specific hardware for a couple of weeks, there hasn't been much motivation (or even information as to how) to support them up until now. But we'll likely see more developers switching from Optix to DXR in the future. Especially if AMD's ray tracing hardware gets better (it's not great at the moment).
Twice I thought I'm lucky and get a card for a reasonable price, but both times the shops send a cancellation, because they took too many orders.
Also NVlink allows you to run two cards 96 GB of VRAM, Virtual Production directors are going to love this!
