The IQ (Image Quality) of the Xabre 400 is very good. With Anisotropic filtering off on the nVidia based cards it's almost impossible to tell the difference between the Xabre 400 and GeForce4 Ti4600! Below are screen shots from two popular games, GTA 3 and Warcraft 3. Please click the images to enlarge them (56k warning!).

On the note of IQ, the 2D portion of the videocard was very good as well, text was sharp and easily readable up to 1280x1024 thanks to the 375 MHz RAMDAC.
