I saw on Anadtech that they have a preview of the Radeon 2 cards. Here is a blurb:
The next statement I'm about to make has been true for most of ATI's cards and it is that the Radeon 8500 has a lot of potential. As usual, that potential is contingent on solid drivers which ATI has not been famous for in the past but they have been improving over time. There is no doubt that the Radeon 8500's architecture and technology is sufficient to allow it to become a GeForce3 killer, however whether or not its drivers will allow it to is another question. Found here.
We'll see how it turns out. Maybe ATI will get some better performing Win2k drivers for their present cards.
