I bought an AMD64 machine a couple months ago to support work on the
Bard VM. I have been using CMUCL (in 32-bit mode) and Allegro (in native
64-bit mode) to do the work.

One consideration about use of Linux on AMD64 is that the maturity of
the 'multilib' implementations varies from one distro to another. I've
been generally happy with Fedora Core 2; Suse 9.1 seems a little more
mature, but feels subjectively slower on the same box.

Another consideration is video friver support; you may want to look into
driver support for video cards before buying your machine. For example,
ATI does not yet provide 64-bit drivers for its video cards on Linux.
