All based on what your requirements and monetary limitations are.

If you're building a system for home, I recommend the low-end Core  
Duo processor which sports dual processors that Xen will happily take  
advantage of.
If you're building a system for work with no budgetary constraints,  
I'd recommend the Pentium Extreme 965 which sports 4 logical  
processors.  Couple that with 8GB of DDR2 PC5300 memory and you'll  
have a hot little box that will comfortably run a handful of  
operating systems with ease.
The language we use at work when talking about processor counts, by  
the way, is sockets, chips, and cores.  Sockets refers to the  
physical receptacle for a chip.  I.e., a motherboard has a number of  
sockets.  In each socket is placed a chip.  Chips have a number of  
cores.  So, with dual core chips you would have two cores per  
socket.  Then, you might state that a motherboard has dual socket  
support.  And if you can put dual core chips in each of two sockets,  
you'd have a four core or four way machine.  And, if each of those  
cores supports hyperthreading (as in the case of the Pentium Extreme  
Edition 955 & 965), you'd have effectively an 8 way machine (but  
still just a 4 core system).
Whew!  :-)

And, yes, Xen will gladly utilize all of the available CPU resources.

What was it you wanted out of all of this?  ;-)
