Very nice machine.
If you have less than 3GB of real memory, you might as well run it in
32-bit mode (i386). There should be no problems.
64-bit mode (x86_64) should work for most things. I haven't tried it
myself, but you will probably see a few problems here and there.
JACK supports both i386 and x86_64, but not connecting both 32 and
64-bit clients in a single server session. That won't happen any time
soon. You might need a recent CVS version for x86_64, to pick up a
bug fix for some bogus compiler optimization options.
