I don't question the value of Xeons. I will say though, that the i7's haven't caused me any problem with heat. My bottleneck tends not to be CPU, but rather IO. Each VM, running its own OS instance and processes like AntiVirus and updates does generate IO. It isn't bad when you have RAID 0 or 10 but if you are simply running with RAID 1, you'll see the difference (assuming spinning HDDs). Shifting to SSD, I've seen RAM to be the bottleneck as to how many I can run simultaneously.

One other note on Licensing. In addition to Windows licensing, you'll run into OT licensing. Nirvana is gracious enough to allow us to run 3 (or maybe 5) instances, but beyond that, if you connect to the license server, you'll end up calling Nirvana Support to get your keys reset or you'll be prompted to get your license keys with each startup. By not allowing a linked clone to access the internet you avoid this. It works for running tests against static data.

On the topic of Windows Licensing, I've noticed that Windows 10 will say it isn't activated. To activate it, acquire a license. In reading, I've found that it limits your ability to change certain privacy settings and get rid of some annoying ads, but I haven't yet seen that it stops functioning. I haven't read through the license to know if Microsoft intends this to be a way of keeping Windows in front of people who don't want to purchase temporary Windows instances or if it is their response to squash piracy. I'm not saying to steal Windows, but perhaps Microsoft is being a little more friendly in its quest to conquer the world.
