It is time for a graphics card upgrade. I've been running my 8800gts 512mb for a while but its time to move up. BF3 and Diablo3 are the games on my radar that I'll most likely be playing. I have dual 24" monitors running at 1920x1200. An I7-930 with 6GB ram and a 128GB m4 SSD. My budget is probably $200, but if there is a compelling reason I can go $250. Just looking for advice as I have not kept up at all with graphics cards. I know nothing right now...
