Unreal Tournament 2004 isn't one of the most recent games on the market, but it was one of the first 3D games to use DirectX 9 and is widely used by other games as the primary graphics engine. Because of this, benchmarking performance in Unreal Tournament gives a good idea about how the card will perform in other games based on the same engine.
All benchmarks were run using the ONS_Dria demo recording the resulting frame rates. Graphics details were all done from the default settings from the installation and in the 1280x1024 resolution. Anti-Aliasing is not supported within the game and must be set at the driver level.
From the results here, it is very apparent that the Unreal Tournament 2004 graphics engine is much more CPU dependent than graphics card dependent. This can be gleaned from the fact that the results are near identical regardless of what filtering settings are used. The one advantage that the 7800 GTX has over the single 6800 GT is the ability to run with the highest filtering settings enabled.
