3DMark 11 is the latest version of the world's most popular benchmark. Designed to measure your PC's gaming performance 3DMark 11 makes extensive use of all the new features in DirectX 11 including tessellation, compute shaders and multi-threading. Trusted by gamers worldwide to give accurate and unbiased results, 3DMark 11 is the best way to consistently and reliably test DirectX 11 under game-like loads.
Honestly I don't know how else you can start. Straight away under 3DMark 11 we can just see some massive performance coming out of the GTX 680 which sees gains of 50% over the previous generation GTX 580 and strong gains against the brand new HD 7970.
The new GTX 680 falls only behind the dual GPU HD 6990, and it's really not by much.
