So I am being really indecisive here as I am just about to pull the trigger on a new build, and am not sure if I should go with two 1.5GB GTX 580's or one 3GB GTX 580. My monitor's native resolution is 1920x1200 (24 inch), and I'd like to be able to turn on as much eye candy as possible with AA/AF. This build is based off of a 2011 socket. One solution is cheaper than the other, but would it be better?
