Looking to upgrade my 7900gtx. I have a core 2 duo e6700, 4gig ddr2 800 OCZ ram, 600 w power supply, Lexa nxzt case and a 22' LG widescreen LCD monitor. Do I really nead a 8800gtx or will the 8800gts or 2900xt do, which should I go for. Thanks in advance for your comments and suggestions.
Depends on the resolution you like to play at. The higher the res, the more graphic memory you'll want. A 8800 GTS is good all around, but GTX prices are coming down. I think I've seen an 8800 GTX for $486 on Newegg.
Check the VGA charts and look at where things fall at the appropriate rez for you.
