Even many of the lower end motherboards will be OK for extreme cooling, low phase count doesn't matter a lot if the phases are good, the rest is pretty much in the cpu & bios options.
What I was thinking, the board is capable of OCing farther than anyone here is going to be able to go on air or water, & with ln2 it will still likely OC as far as the chip will go.
I haven't done any real stability testing, just some bench stable stuff so far while learning the board.
One thing i love about haswell is the ability to run super fast memory. Bloomfield refuses to go over 2200 and i plan to run 2600+ with Haswell.
