DiRT 3 was released quite recently and has received a lot of praise from gamers and reviewers across the globe. It is the latest iteration of the Colin McRae Rally series, despite Codemasters dropping the Colin McRae branding. It supports DirectX 11 which enhances detail and brings a number of other visual enhancements to the gaming experience.
It seems that DiRT 3 is also optimised for the AMD hardware as we achieved significantly higher framerates with the FX-8120 than the Core i5 2500k
