uTorrent 3 alpha goes 64-bit
So what does the 64-bit version get you? Not a lot, as far as your torrent experience is concerned. Support for a larger disk cache is about it, along with the fact that Windows won't have to do any x86 emulation to run uTorrent. Commenters have reported occasional crashing, but this is an alpha release we're talking about -- so that's to be expected.
