... Crysis on high settings, i'll gladly do it...
I tried the Crysis Pre-Release demo on my PC and it was very comfy to play with when all options are set to High. There are a few frame drops I noticed when lots of stuff is flying around but aside from that it runs nice and easy.
GIGABYTE M68MT nForce 630a Socket AM3 Motherboard
AMD Phenom II 1055T Six Core Processor
Corsair CMX4GX3M1A1333C9 XMS3 4GB DDR3 RAM
Western Digital 500GB Caviar Blue Hard Drive
DiabloTek Elite 450W PSU ATX Mid Tower Case
Total Cost of Main Parts: $335 without rebates.
Then I added an AMD Radeon HD6770 and this runs everything I throw on it. But then again, I'm not a PC gamer anymore so I can only confirm that I can run Crysis at 25-40fps on 1280x720 8xAA and DJMAX Trilogy at 1920x1080 at Maximum settings at 650-1500fps.
