When was the last time you ran Crysis 2? I ask, because I just reinstalled it lastnight along with the high res textures and DX11 patches. What surprised me is that I'm getting nearly double the frames on a single 680 in 3D vision, as I was with 470's in SLI a few months ago. I'm not sure how, but Crysis 2 got a big boost in performance at some point. A 680 with 3D Vision and max settings (no AA) and I'm maxed at 60 FPS almost the whole time (With 3D vision, you are always V-sync'ed).
