I would expect so.
Considering he's doing it on a dual core machine, I'd expect so too.

What would have happened if it was a quad core [before hyperthreading] and the VM had 4 cores?

Also, wPrime is a program designed to load the CPU, not a real world scenario. Remember, in post #5, I said

Sorry that I was not clear - the W7 VM testing mentioned above was done on the i5 system listed in my specs. I figured if someone was play W.O.W on the XP VM, they could lag the host if there were not some restrictions put in place.
