I just bought a PNY 7900 GS to replace my old X850XT PE (AGP) cuz I changed mobos to a PCI-E mobo. For some reason I get lower fps with teh 7900 GS than the x850xt pe in counterstrike. I was getting like 80 fps with max settings at 1024x768. Now I get like an average of 32-33 and lag at moments around 17fps. Whats up with that? Any ideas? Not a good replacement for the x850xt pe?
