DiRT 2
DiRT 2, a lovely-looking racer and one of the first games to use a DX11 path, offers improved visuals whilst burning through the London map.
DiRT 2 perf. is slap-bang in the middle of the Radeon HD 6970 and HD 6950. In short, pulling out all the stops on a GeForce GTX 560 Ti results in a super-fast card that challenges - and often beats - genuinely high-end GPUs.
