I know there are a few other PAZ77 Mobos but I am unsure about if there are any differences between any of them.

All I need is something that will support SLI in the future.

Two extra internal USB 3.0 connections for the Pro seems to be about it, but both support SLI (x8, x8 with two GPU's installed in the 3.0 x16 slots on both boards).

I may get the one that is cheaper than since USB 3.0 ports are not that important to me.
