What can you afford? The more cores you have, the better, as you
reduce the amount of state swapping as different VMs get a bite at the
cherry. Although I'm an AMD fan, at the moment Intel seems to be
winning in the bang for the buck stakes (though that's liable to
change from day to day). My general attitude when buying CPUs is to
buy one step back from the bleeding edge, as I reckons that's usually
the peak of the price / performance curve.
