"Let's not lose sight of the fact that ATI performance isn't relatively poor at all. I think Kyle himself said that even the X800pro delivered 'great' performance, and Carmack said in the HardOCP article that there's more to consider than just frame rate. The frame rate difference even today is so minor, it's impossible to tell without diagnostic tools - ie: the end user experience isn't affected. And with ATI you get full-precision enabled all the time - we don't do PP (on R3XX and R4XX) like some of our competitors. It's also important to note that most of today's games play faster on ATI hardware, and you can expect that to extend to other 'big title' games expected this summer."
