Quake III Arena is a First Person Shooter (FPS) that revolutionized gaming as we know it. Using multiple light sources and having graphics textures that can fill videocards, even after 3 years it's still able to bring a cutting edge system to its knees.

Quake III loves memory bandwidth and it seems like the KT400A's memory controller is tuned more for performance then the KT400. They're still quite a bit slower then the nForce2 based 8RGA+.

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 performance differences between the KT400 and KT400A are much smaller in UT2003 but they are there.
