Hi Foofighters, i just recently upgraded my video card from a Nvidia
6800 (256 mb) to a BFG 7950 GT OC (512 mb) made a hugh difference on my fps,from 30 fps to over 90 fps (1024x768)Perhaps not as good as the 8800 gts, but very close and less expensive with out having to upgrade your power supply as well IMHO. My Rig: P4 3.2 HT,2 gigs of ram(533)Windows XP Pro,and above mentioned card.Since there is no current DX 10 games out save you $ on 2ndGen. DX 10 cards when they come out in the near future
