- Testbed DirectX10

• 3DMark Vantage

We used the three built- in benchmarks to test the performance of each graphics card. We measured the performances at various resolutions using the "Performance" and up to the "Extreme" settings.

• Company Of Heroes

We used the built in benchmark with all the details maxed out.

• Crysis WarHead

We used the FRAMEBuffer benchmark tool for the resolutions of 1280x1024, 1680x1050 and finally 1920x1200. We used all the possible quality levels to get an idea what the graphic card can do at each corresponding resolution.

• Far Cry 2

We used the built-in benchmarking utility and maxed out all visual details, under both DX9/DX10 and settings up to 16x AA/16x AF.
