Quake III: Arena v.1.32	Source: ID Software

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.

Each of these tests was run with the 'four' demo.

QIII Arena - 1600x1200

NVIDIA GeForce FX 5900 Ultra	246.4
NVIDIA GeForce FX 5950 Ultra	254.8
ATI Radeon 9800 Pro	230.1

4xAA 8xAF	FPS	Ranking

Sapphire ATI Radeon 9800 XT	145.4

NVIDIA's GeForce FX 5950 Ultra establishes a two percent lead at 1600x1200, which can hardly be considered perceptible. In order to apply a little more pressure to the hardware in question, we enabled 4x multi-sample anti-aliasing and 8x anisotropic filtering in each of the cards' driver control panels.

Running the same benchmark, the roles reverse, and Sapphire's RADEON 9800 XT picks up a seven percent lead at 1600x1200. Admittedly, it'd still be hard to tell between the two during actual game play.
