Unreal Tournament 2003 is the sequel to 1999's multiple 'Game of the Year' award winner. It uses the very latest Unreal Engine technology - where graphics, sound and game play are taken beyond the bleeding edge. Unreal Tournament 2003 employs the use of Vertex as well as Pixel Shaders and it's recommended that you use a DirectX 8 videocard to get the most out of the game.

The X800XL core is great for gaming, as we've known for a while. The MSI RX800XL-VT2D256E sees a perceptible increase in the 'flyby' scores when overclocked, but otherwise OC'd and non-OC'd scores are virtually identical.
