For me, a multi-cores machine is a must. In one hand, jack1 on a
32 bits single core machine and a rt kernel, give me very little less
latency, than jack2 on a 64 bits 4 cores machine and a "regular" kernel,
with rt enabled via cgroups. Both machines have the maximum amount of
RAM they can handle and are running fvwm-crystal as desktop. On the
other hand, this last machine give me the opportunity to be able to do
whatever I want, as example run a server, have emerge that compile
hugin or libreoffice, and run rt applications, all that at the same
time on the same machine.

To do the same with a single core machine, I must have a double boot
with 2 kernels, a rt one for the audio applications, and a non rt one
for the server and emerge (I don't try it with a cgroup enabled
kernel).
