Gigabyte Gaming 580 is running a steady 29-30mh/s, Aorus is absolutely no different, MSI Armor I bitched about before are actually the best cards at 30-31mh/s. Red Devil's arriving tomorrow.........and I'm out of boards.
So far the MSI X170a gaming m5 has been a clusterfuck bitch trying to get to run more than 4 cards, instead of 7. Still looking for a solution :\
