Ok, my problem is that my system performs fine under normal situations, but is really bad at gaming. The only games I can play decently well are pretty non-demanding (WoW, UT2004). Farcry and bioshock throw me into unplayability. I would love it if someone could point out what my bottleneck is (vista thinks its the processor). My basic specs are: Asus - P5ND2SLI mobo Pentium D 930 (presler) 3.0ghz Maybe an E6600 is in order here kingston valueram 2.0 ghz (667 ddr2 5300) evga geforce 6600 gts step up program waiting list here I come psu is some 550-600 watt decent brand, I can't think of it right now. running vista 32-bit (64 on the way). Thanks for your help I've tried OCing and I can't get much performance out of this system!
