I just upgraded from 800XL to 7900GT.
Decided to go with BFG OC 7900GT for $340. Its really hard to find these on sale, and when they appear you literally have 5 min to get it before they are sold out again.
I ran both cards on the same PC. A64 3000 939, Asus SLI board, 2GB of RAM, 2x 80GB SATA in Raid0.
Results for 3D Marks 2005 (free version) :
ATI 800XL - 4652
BFG OC 7900GT - 7565
Im impressed, I thought it wasn't going to be much of an upgrade but this card ROCKS. Love it.
I can actually play COD2 at 1680x1050 with everything maxed out. I was getting 30-40fps.
Played HL2 and DOD:S and both games run flawless and look beautyful at the same res with everything maxed out (AA x4, AF x4, VS on, HRD Full)
My CPU is a bottleneck as it tops out in most games. I can't wait to get the X2 3800.
