Hell, then do what I'm doing. Buy it right now and get some solid gaming out of it. I've saved so many games that I haven't touched because my 6800 go could barely handle them on low and now that i just built this rig I'm trying to get these games finished so i can either part it out, or let it sit... Just beat Crysis, Dead Space, and Assassin's Creed. Im working on Bioshock, Company of Heroes OF, GRAW, and Fallout3. This card owns em all, except Crysis of course, but I game at 1920x1080 and nothing lower.
Edit* also I play DS, Bioshock, and Fallout3 with Vsync on and they hold 60fps solid on max graphics at 1920x1080, however, DS has no option to force AA, Bioshock I play at 2xAA and FO3 on max graphics with 2xAA and 15 samples AF will dip to 50-55 in outdoors but i just lower the settings to High which I can't tell any difference, and it maintains 60fps at all times, of course you could turn vsync off and get much better frame rates, but i HATE screen tearing. AA doesn't bother me too much as I have a 21.5in monitor so my pixel pitch is very small and less AA is needed to smooth out my jaggies.
