ATI Radeon X800 Pro
 

The X800 Pro is definitely no slouch. Smooth performance in most games
with the image quality turned up and the resolution maxed is something to
be proud of. Based on our results, we have no problems recommending this
card to our readers. While some benchmarks have shown the 6800 GT to be
faster, the actual gaming experiences with the X800 Pro were positive.
