How you get 30MH from 1060?
Apparently by raising to 120W...

Typo I guess, it makes sense if it should be 1070 at 120W with 30.5 MH
I get 23.5 in average my 9x1060 with micron at 75W, so 1060 with Samsung would score high in the MH/W scale every day.
But 1080ti will have a decent resale value for longer (but 3x cost for 2x hashrate and close to 3x power??)...
