Here Ill be posting screenshots of all the prettiness of the Dx11 update So far its over 60 images of things such as lighting, tessellated textures, and just awesome looking vistas. This game really is beautiful!

RIG:

CPU: I7 950
GPU: GTX 480 -OC to 800mhz, 1920 memory oC
RAM: 4 gig 1333 mhz
OS: W7-64 bit

Crysis 2 settings:

Everything set to Ultra, High res textures, Max motion blur, 1920x1200 resolution.

TBH I barely notice any difference between Dx11 Ultra and Dx9 Extreme

To each his own I guess, although some of those screens the difference really cant be argued. One has tessellated textures creating a real sense of depth, while the other does not.
