What he has done is quite difficult to do these days because of motherboard availability. In some cases an LGA1366 motherboard can cost more than original retail. It's insane. But the performance is great. But if you have an older first gen motherboard, you can get a 6 core Xeon for as little as $40 on eBay. Great upgrade.

What's really insane is that you can get several 10 core LGA1567 E7 Xeons for $20 apiece. If you have a end-of-the-line recycler in your city that will custom pick stuff out of the pile for you, you can get a very scratched up electricity sucking "hog" for next to nothing.
