The 64-bit version of Windows 7 beta has hit torrent sites according to an article that was posted earlier today at Ars Technica.

Performance should be quite high if it is like the 32-bit version notes Emil Portalinski, the author of the article. He also writes that this leak is another slap in the face to testers who are waiting for the beta version of Windows 7.

There is an mp3 corruption bug in build 7000, the beta version, but Portalinski writes that a patch should be released any day now so the testers would not have to deal with this problem once Beta 1 is released.
