The performance is quite amazing.

World of Warcraft runs nicely under Windows giving an acceptable 20 fps at 1440×900 24-bit color 24-bit depth 1xmultisample1440×900 24-bit color 24-bit depth 1xmultisample with everything turned up high or on. Dropping down the anisotropic to mid-point and turning off the full-screen glow effect and smooth shading bumps that up to 30 fps.
