I have this card running with 10amd 580s, stable and mining zec at 3KH/s.    Just picked up 3 more xfx cards to add to it after I get drivers installed.   Hoping they release the update to add the remaining 6 cards.   I don't want to mix the Nvidia cards as simple mining doesn't allow that.   But for now I'm up and running smoothly.  Anyone have info on the update?
