Well, by the time Crysis is released I should have my QX6600, new mobo, and new ram. Heck, I might even have dual GTXs by that time. If not, these two GTSs will do great I'm sure. Honestly, I'd expect my 8800GTSs to do 1600x1200, 16xAA, 16xAF, with most (if not all) in game options maxed. I'll be quite bummed out if they don't manage playable frame rates at those settings.
And if they don't, then I'll just have to get dual 8800GTSs now wont I?
