By combining DirectX8 support with completely new graphics, it continues to provide good overall system benchmarks. 3DMark2001SE has been created in cooperation with the major 3D accelerator and processor manufacturers to provide a reliable set of diagnostic tools. The suite demonstrates 3D gaming performance by using real-world gaming technology to test a system's true performance abilities. Tests include: DirectX8 Vertex Shaders, Pixel Shaders and Point Sprites, DOT3 and Environment Mapped Bump Mapping, support for Full Scene Anti-aliasing and Texture Compression and two game tests using Ipion real-time physics.

Higher numbers denote better performance.

3DMark2001SE Benchmark Results with AF
	Video Card	FPS	Ranking
1.	Asus V9950 Ultra 2x AF	15112
2.	Asus V9950 Ultra 4x AF	14750
3.	Asus V9950 Ultra 8x AF	14384

AF does not really lower 3D performance that much thankfully.

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.

Quake III Arena MAX 1024x768 demo001 with AF
	Video Card	FPS	Ranking
1.	Asus V9950 Ultra 2x AF	325.1
2.	Asus V9950 Ultra 4x AF	303.8
3.	Asus V9950 Ultra 8x AF	286.9

AF seems to degrade OpenGL performance a bit more than in Direct3D.

1.	Asus V9950 Ultra 2xAA, 8x AF	13239
2.	Asus V9950 Ultra 4xAA, 8x AF	12409

Those are certainly some awesome numbers. I remember when breaking 10k was hard!
