The upcoming RV670XT GPU is shipping, FUD Zilla reports. This chip will feature DirectX 10.1 support and will be available on November 15th.
HD38x0 will end up slower than 8800GT but at the end, we expect it to be cheaper 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.
