Thanks for confirming how stupid it is to spend $9000+ just on GPU's to get 460 MH/s when you could spend less than half of that on 16 RX 580's to get the same amount of hash and better dual mining performance to boot.
Or take the 1080 ti's and mine other coins
No one should mine eth with 1080 ti's
Does not pay
Even on ZEC you are looking at an ROI of 10+ months just to pay off the cards. I would rather put together RX 570 rigs at 1/2 the cost and an ROI of 8 months.
There are coins that work for 1080 ti's
I can do very low power setting of 50 percent on 1080 ti's and mine them . I earn more with them at 50% then mining zec at 70%. And no amd matches them.
But I already roi 'd my 12 1080 ti's so earning 3 dollars a card using 130 watts is fine for me.
If you do the math 3 x 31 is 93 per month. 130 watts is 10 dollars a month this is 83 a month x 12 cards is about 1000 a month on free gear.
Of course the coin I mine could crash and burn and I would need to find one or fall back to zec
