From The Inquirer:
BENCHMARKS for ATI's Platinum and Pro products appear to have leaked onto the web.
Here
Apparently these images are leaked from THG's presently embargoed review of the ATi Radeon X800 PRO and X800XT Platinum.
Seems it wins by some but gets beaten in some. So far (I'm working my way through all the images) there isn't a clear winner (and thats comparing the 6800 Ultra vs X800XT!!!!!)
