This is a link to AnandTech.com for their review on the new Radeon X850 series and the X800XL personally i think, with the price/performance ratio in mind, the X800XL (400mhz/1ghz, 16pipe 256mb, $350) is the best one there, but the X850 Pro (520mhz/1.08ghz, 12pipe, 256mb, $400) is crap a card, even with an approx. 30% higher clock speed and a $50 price increase, it's still beat out by its younger cousin, the X800XL (probably because of the 4 extra pipelines).
