Crysis 2 may not have lived up to the expectations set by its predecessor, but with the DX11 patch and high-res textures, it's a gorgeous-looking game.

A different set of titles may deliver different results, but for the third game running, CrossFire performance is a disappointment.

Sapphire's Radeon HD 7950 OC once again shows its ability by coming out ahead of EVGA's GTX 580 SC, but put two together in CrossFire and performance actually decreases.

We've re-run the benchmark multiple times - on both P67 and X58 platforms to make sure there are no bottlenecks - and could never get Crysis to fully utilise both Radeon GPUs. AMD tells us it is "investigating" and will provide a solution or further comments soon.
