I prefer Crysis 1, but maybe there is a good Crysis 2 Graphic mod out there?

Crysis 2 Dx11 was the first Next-Gen game released, as BF3 will be the second, now what we're really talking about here is Game Engines, so what you have to do is keep an eye on the 'CryDev' site and have a peek at what the CryEngine 3 is capable of, just wait and give the Devs time to get to know the engine and we'll see more Next-Gen stuff in the near future.
Crysis2 DX11 on Ultra has yet to be beaten, takes 2x 580s, not one 560, when running modern games apart from C2 with 2x 580s they don't even go full clocks if you got 'adaptive' set in the Nvidia Control Panel, Crysis 2 uses em' up no sweat, that's physical verification that the CryEngine3 is boss(at this point at least, we'll have to test Frostbite2 and make our own minds up about that one).
