Pixel Shader Version Supported: Mix PS1.1, PS1.4, PS2.0

Trilinear filtering optimisations afford the XFX a decent boost in performance in 3DMark. Look for similar increases in other applications.
Overall, the XFX has no problem outrunning an X800 PRO, which is to be expected.
Call of Duty
Vendor: Activision - (Website)API: OpenGL
Pixel Shader Version Supported: PS1.1 class

We're CPU limited in the HEXUS custom demo so the optimisations afford the card very little if anything at all initially, with the X800 PRO well able to keep up. At the upper setting the XFX gains good ground over the X800 PRO and the trilinear optimisation kicks in for increased performance.
Very similar performance to the Gainward at 450/1200.
