I'm using 10 GTX 1060 in my rig running under Ubuntu 16.04



I get an average slightly above 230Mh/s

I have cards from different manufacturers (EVGA and MSI) so settings may vary.
Usually max power 75W, core clock -200, memory between +1100 and +1600
I have Samsung memory on all cards.

EVGA model is a bargain:
EVGA single fan

Models from MSI:
MSI double fan / armor
MSI Single fan

Power meter in the wall indicates 850-900W for the whole rig (motheboard, gpu, psu, ssd, cpu,...)
