I'm primed and ready to get into a Sandy-E setup but I'm on hold for the CPU purchase. I intend to use (and already have) an Asus X79 Sabertooth for the build. So the real choice is between the 3930K and the 3960X.
My 24/7 goal is acutally pretty low - 4.0 - 4.5 HT enabled. If i can keep SpeedStep and full sleep capabilitiy, that's a plus too.
So in all reality, with gaming being the 'hardest' thing this rig will do, the 3930K is the way to go. But who's going to get it in stock and when is it going to be there?

It seems there just aren't a lot of places to buy a CPU anymore. I don't have a Microcenter close by anymore (6 hour drive to the one in Atlanta) and all the old sites I used don't seem to be there anymore. (Anyone remember Anandtech--I think that was their name)
