Two logical cores = hyperthreading. ;P On that note, you want the AMD dual cores as well, because they are much better designed (they have the crossbar architecture all ready to drop in additional cores, whereas the current Intel dual-core are really ugly hacks and perform terribly compared to the AMD ones) -- gentoo-amd64@gentoo.org mailing list
