A more balanced look at the X1800XT..

I found this one far more informative - it talks about heat, noise and 'real world' performance (rather than timedemos) and seemed to stay pretty neutral (neither pro-nvidia or pro-ati) - than most of the 'reviews' of the new ATI architecture. I got the feeling that overall they felt that the cards are pretty evenly matched, and user preference will determine which way to go. I definitely think ATI's new architecture will be a lot more interesting next year when they add some more pipelines and (hopefully) ship against the G71 from nVidia.
