I've been using an XFX 7800 GT in the following system for a bit now:
Antec P180
Enermax Noisetaker 485
Abit AN8-Ultra
AMD Opteron 148 (stock speeds)
2 x 512 Crucial Ballistix Pc3200
250gb Western Digital SE16 HD (SATAII, 16 mb cache)
XFX 7800GT (factory OC)
Sound Blaster Audigy 2 ZS
Windows XP Home Edition
And I've been getting some disappointing gaming results compared to what reviewers of the card noted in their benchmarks. It honestly seems as though the card is nowhere near as powerful as it should be - for example, I'm getting ~60 FPS in Doom 3 at 1280x1024 w/4xAA whereas reviewers were getting upwards of 80 and 90. In games like Call of Duty 2, the lack of performance is even more noticeable.
Everything is fully patched. I have all the updates downloaded for Windows, the latest drivers, et cetera, and I can't seem to place my finger on what might be causing such a performance handicap. Is it possible that my CPU might be bottlenecking the performance? Would getting an X2 help?
