I got 18 of them Zotac P106-100 mini single fan currently on 3 x Win10 rigs 6xGPUs (23-24MHs per card or 20-21MHs on smOS Linux), they are mining ETH together with the Zotac Minis 1070s (32Mhs on smOS).

IMHO, the NVIDIAs are very stable, cool and easy to OC, I am very happy with them and spend less time baby sitting them compared to AMD RX480s and RX470s which I had to do custom rom mods and tweak them to kingdom come. The RX farms are stable now, a dozen of them upgraded to 12/13 slotters and I am not going to be disturbing them anytime soon.

I am spending most of the time now on the 1080tis and experimenting on ccminer algos.

Safe to say, that my future investments will be on NVIDIA cards and less on VEGAs....
