Nehalem is the chip architecture.
Both i7 and the newer Xeon ie 3500 and 5500 series are based upon the Nehalem architecture.
The i7 is the Desktop version while the Xeon in the Server version (ecc ram compatible among other things)
Keep in mind for a dual cpu setup you would need an X version ie X5500 Xeon. They support two QPI links.
Here is a good read to get you a little acquainted with the technology involved.
iXBT Labs - Intel Xeon "Nehalem" - Page 1: Some history
Waiting for the server guys to give you some feedback on potential builds as I am more of a desktop and htpc guy.
I was just making sure you did not want a dual cpu for a killer gaming system which it would not be.
