I edited my post.. it's 11mhz per card.
Some extra info.
23,5Mhz @ 60Watt (core down to 850) per card on Ethereum, 25Mhz @ 100watt (stock clock) and 30Mhz @ 200watt (core @ 1100)
Don't think Nvidia can beat that ;-)
But pricy card none the less..
Some really nice numbers there...
I thought my nvidia 100KH/s@600watts from the wall was good...
