I'm probably going to go the direction of SBS2011. I'll have to look into the MS hypervisor and desktop solutions. The reason why my small business server is on the dual Xeon 5405 is that the Core i7 980 is a lot faster and has the equivalent of 12 cores. It actually replaced another dual 5405 server that had less disk capacity. Testing speed to the database with Amazing Charts Utilities, it improved from an average of 0.6s to 0.2s

Also, note the newer Core i7 980 is near equivalent to the newer Xeon chips we'd like to try. The difference is ECC memory, ability to use in a multi-CPU socket system, and a few other odds and ends that are more important to super computing but don't really help us standard users.
