ATI's Radeon X850 XT Platinum Edition
It's when you consider the performance on offer, clearly the most that any single card on the market can offer, that the niggles start to fade from view. You're CPU limited a bunch of the time with the board which means you're really going to want to pair it with something like FX-55, but if you can afford one, you can generally afford the other. It doesn't get faster than X850 XT Platinum Edition, it's as simple as that.
Overall, ATI raise the bar yet again. Performance is incredible, the cooler made nary a peep above its settled speed in my test system and I have a lot of lust for dual DVI right now.
