Thanks for the links.
Can you (or anyone) can tell me if I'd see a benefit running vmware on the i7 over the i5. I'm thinking the hyperthreading of the i7 may be beneficial, provided vmware is written to handle it.
I would say the i7 930 for sure. As you have more than one virtual os running it pulls harder on your system. The i7 has much more head room and with allow you to do more. As stated above the amount of ram is very important, so be sure to take full advantage of the 6 ram slots that the socket 1366 motherboards have.
