i have a 26 inch sony screen, cool keyboard and mouse, got a 8600 gt screen card, but i recon that is not too important, or is it if you have a system like this. I have a 32 bit os so i want to get a new one that is 64 bit, but then, would it be vista, win 7 or xp . Of course xp is cheaper, but for how long will this still…
