I'll probably build a dedicated rig pretty soon, from what've read the 1080s mine about 100%+ what you would get from the 1060, I'll likely get one of those for my main gaming rig and relegate my 1060 to a mining rig and get it some friends to hang out with in the rack. I'm thinking 4 1060s to start with as a dedicated rig, if you're not too fussy what you mine seem to be on par with the AMD 480s.
