DMM Japan most likely have it already ...
and they are test running it in their farms.
F3 specs..
650MH/s @ 750Watts

That is like a full 10-12 GPU RIG. anyone know what is gonna be the F3 price?
As stated above, when taking the 3x32GB boards as true (total 96GB) it would give a theoretical maximum of around 230MH/s.
It's main advantage could be lower cost than equivalent GPU hashing power at around 60% of the power usage.
