ATI knows that it is only two weeks behind Nvidia and it is doing the final preparations to launch its HD3800 generation. ATI has an ace of spades up its sleeve: the DirectX 10.1 support. As you already know, D8P/G92 based 8800GT don't support this new DirectX 10.1 or Shader model 4.1.
HD38x0 will end up slower than 8800GT but in the end, we expect it to be less pricey at the same time. ATI plans to launch toward the middle of the month, probably on the 15th, and Phenom should be launched just days after that date, if not even simultaneously.
The reference and production Radeon HD 3800 generation, RV670 based cards are finished and they are on the way to reviewers as we speak. This is not D day, this is D week.
