personally, I would go for the most memory.  Usually, you can remove 
CPUs if consumption power is an issue.  The difference in CPU speed is 
negligible.
IMO, the limiting factor is not CPU but RAM available to a virtual 
machine.  it would be nice if there were some way to let memory float 
between virtual machines based on need.  In the other hand, it may be 
there already and I just haven't figured it out.  I'm still running 
2.0.5 because of some of the noises I've seen about lvm and I'm looking 
for a quiet moment when I can risk killing my xen machine.

The result of the duopoly that currently defines "competition" is that
prices and service suck. We're the world's leader in Internet
technology - except that we're not.
