XFX 9800 GTX Black Edition 512mb
Call of Duty 4 is a stunning DirectX 9.0c based game that really looks awesome and has a very full feature set. With lots of advanced lighting, smoke and water effects, the game has excellent explosions and is fast and furious, perfect for our test suite.
F.E.A.R. is a game based on the Lithtech Jupiter EX engine. It has volumetric lighting, soft shadows, parallax mapping and particle effects. F.E.A.R. is a little older game so the 9800 GTX should handle this well and look fantastic.
Bioshock is a game based on the Unreal Engine 3. It uses some DirectX10 features such as awesome water and smoke effects. The detail level in the game, combined with a frantic pace makes for an excellent benchmark. I've found Bioshock behaves strangely sometimes in benchmarks so it will be interesting to see how it does here.
