Hej James,

i'm running an MP System since a long time, very stable (NetBSD is stable
with UP anyway). 
The Advantage of an MP System is not that much at a glance.
You get more speed during compiling Stuff (kernel, programs,) but only if
you use appropriate Options (make -j 4, e.g.).It's fun ;)
In your case I'd prefer the AthlonXP CPU.
