- Dirt 2 (DirectX 11)

Colin McRae: Dirt 2 (known as Dirt 2 outside Europe and stylised, DiRT) is a racing game released in September 2009, and is the sequel to Colin McRae: Dirt. The game runs on an updated version of the EGO engine, which powered Codemasters' Race Driver: Grid as well. The engine features an updated physics engine and makes pretty through use of the DX11’s tessellation abilities.

We used the latest Dirt 2 game patch and used the built-in benchmark for the resolution of 1920x1200, various quality levels and with AA enabled.

DIRT 2 is another poor showing for the 6790. With NVIDIA’s normal performance advantage here the GTX 460 is ahead. Of course, at nearly 57fps at 1920 the 6790 should be playable for most gamers at that resolution.

Regarding the GTX 560, the card enjoys a significant lead over the 6950 1GB at 1920:

Rebellion has released a standalone DirectX 11 PC benchmark test based upon its shooter Aliens vs. Predator. The benchmark test requires a graphics support supporting DirectX 11, which are used to produce such fancy features as tessellation, advanced shadow sampling and DX11 anti-aliasing.

We used the default settings of the benchmark (resolution: 1920 x 1200, Texture Quality: 2, Shadow Quality: 3, Anisotropic Filtering: 16, SSAO: ON, Vertical Sync: OFF, DX11 Tessellation: ON, DX11 Advanced Shadows: ON, DX11 MSAA Samples: 1).

- Lost Planet 2 Benchmark (DX9/DX11)

The Lost Planet 2 benchmark allows you to measure the performance of your graphics card using a a pre-configured route within the game. The benchmark can be run under both DX9 and DX11.

Here is the first game in which the Club3D HD 6790 seems to have an edge over the Gainward GTX 560 Ti 2GB, at least under DX9.Under DX11, the HD 6790 is significantly slower and the GTX 560 Ti 2GB competes with the HD 6950:
