SL3XM's L2 cache though less in size has its speed doubled compared to
that of SL364 according to Intel. Therefore, _in theory_ you're better off
with SL3XM and it uses less power (less heat?). But in practice, like web
and mail, I don't think there would be a _dramatic_ difference in
performance between the two processors.
