Crysis is seen by many as the poster boy for DirectX 10 and it will make your system quite literally fall over crying if it's not up to – it’s a monster of an engine! It doesn’t come as much of a surprise then, that the graphics are something special – they’re above and beyond anything we’ve ever seen in a PC game even still. We used the latest 1.21 patch and range the game in 64-bit and DirectX 10 mode in a custom level run through.

Frames Per Second - higher is better

Four extra frames per second is what a 50 percent overclock gets you - not much, but it's still "free" performance and the fastest thing on the entire table by over a frame per second.
