To me, pool side, Spmod6 is still the best mining signatum (20x 1080 80x1060 40x1070)
What is your hashrate for each card?
19.2 1060
29.8 1070
35.5 1080
and those numbers are fairly consistant with pool stats
With 1070 which is your TDP, GPU and Memory clock?
With TDP 80, gpu +150 and Memory -1000 I have 27,8 MH
