Unreal Tournament 2004
We begin with an oldie but a goodie, in the form of Unreal Tournament 2004.Without anti-aliasing and anisotropic filtering, all three of our boards are CPU-bound, so there is nothing to show between them. The Gigabyte 3D1 does lag behind slightly however, presumably due to the extra driver overhead which comes from using SLI.
The 6800GT and Gigabyte 3D1 both remain CPU-limited, even with 4x AA and 8x AF enabled. The standard 6600GT drops away at 1600x1200, showing the added power of using dual 6600GTs on the 3D1 for the first time.
