Again, I'm confused. I've run it on my old 9650 Core2Quad, a Core2Duo, a Phenom X4 (with the TLB bug, and it still worked), An old Opteron dual core, an E3-1230, A core i5-2500K, And multiple VM environments on each of the above platforms as well. (Ubuntu x64 in Virtualbox on either an Ubuntu x64 host or a Win x64 host). I've not installed a 32-bit Ubuntu variant in maybe 4 years now. Heck, I only install 32-bit windows on my old laptop because it was a Pentium M and 32-bit only.
