These are on clearance for $250, if you can find some it would be very worth your time to pick one up. Ive been selling the Desktops without the 1060 for a solid $300+ on eBay.
All of mine came with Samsung ram and my god.... for some crappy OEM card these things are crypto monsters! Everyone one of them is maxed out in MSI afterburner at +1000 mem!
Hashrates:
Dual mine Eth + sia = 24.7 Mh/s Eth and 247 MH/s SIA.
Eth only = 25.2 Mh/s or higher.
Lets be real, any 1060 3GB that hashes over 25 mh/s is the holy grail of 1060 3GB cards.
