Windows 7 build 7000 64-bit version hits torrent sites

From Ars Technica -

Almost two weeks after Windows 7 build 7000 32-bit was leaked, the 64-bit version has hit torrent sites. The first 7xxx build marks Windows 7's beta phase (6xxx builds were pre-beta builds). Build 7000 was compiled on December 12, 2008, at 2:00PM, and many believe this is the build that Microsoft will be giving its testers. If the 64-bit build is anything like the 32-bit, performance should be quite high.
