I’m running a pair of MSI R7 370’s and get better rates from nsgminer (~280 per), though you have to be more careful of overdoing it with intensity settings & heat than sgminer. I run the 15.x crimson driver on win7, so can’t help with win10, and don’t know if the 16.x drivers are ok or worse with neoscrypt like they are with ethereum ethash on any win version.
I’m also running a pair of EVGA GTX970’s with the djm neoscrypt miner, and get 650 per card without pushing them, 700+ if I do.
