I'm running nothing but 1070/1070ti + 1080ti cards on all my rigs, but got a bit frustrated about the rip-off charges for new cards at present, so just bought x6 1050ti cards for a new rig.

Using Simple Mining OS, mining Equihash, Core 110, Memory 800, Power 100 and getting 1020sols at 440 watts. It's not great when you looks at the sols per watt (compared to my other rigs), but the rig is earning. But these cards are cheap, so that kinda makes me feel better 

I'll see if I can tweak it a bit when I get the time.

... waits patiently for prices to come back down to earth again ...
