I have never mined Etherium with my 1080/1080ti's due to the memory both use it's nowhere near the top of the list profit wise (1080 is around 24hash and a 1080ti around 35 for Ethereum).
With the later AMD cards getting back their speed from new firmware to sort the DAG issue then the difficulty is only going to rise more for Etherium as they are mainly 1 trick pony cards so the return is only going to get lower unless Etherium goes up in price a fair bit (which has gone up around 50% in the last month it;s still $100 down on where it was a few months ago)
I've actually got around £550 the last month although around 20% of that was due to the Bitcoin price as I was holding onto mine as Bitcoin seemed low to me as the market was just correcting itself after the gain. I personally feel Bitcoin is again too high after a massive gain and new record high in the last month so again it's going to correct itself so have sold it all off for now.
I deffo get more than £10 a day (total) from my 5 cards at the moment (averaging around £14-15 without electric costs or £11.50-12.50 with them.
So £1.50 from a 1070 doesn't sound bad.
Power wise my cards work best with around 66% for the 1080 and 75% for the ti's any more than that and I don't feel its worth the boost from the extra heat and stress it puts on the card to keep it cool etc.
I honestly couldn't tell you what coin I'm mining at the time as it can change so often, Until recently tho it was best to mine the newer SIGT coin by far and for a few weeks I was averaging around £15 a day AFTER electric costs were taken off.
The NVIDIA cards are much better for mining IMO as you can mine so many coins with them, All the cards scale up well mining wise as well on most of them, looking at a 1070,1080,1080ti they all have around the same time to break even as each other (around 7 days difference max) so I have no idea why almost everyone got 1070rigs etc as when it comes to selling them off there are going to be soooooooo many 1070 cards on the market, If you started off with a 1070 fair enough but with the ROI being around the same time on all the cards to go with the cheaper option that everyone has purchased (and driven price up on seems daft at the selling off point), Personally I'd rather have a 1080ti to sell off even if it took 7 days longer to break even, At that point I've got a card worth almost twice as much and a top of the range card to sell to gamers and not an average one.
Like I said there are so many coins to mine tho, Ethereum isn't on the 1080 or 1080ti radar at all, to name a few that are currently better.
Zcash,Zencash (pretty much all the Equihash based coins)
Hell even Monero after the massive price increase after being listed on new exchange
For a 1070 tho it's very different only Zencash and Zcash and SIGN are currently better so it really depends on the card. For me tho I want a card that can do as many coins decently tho as possible so it still makes a nice profit if I have to change to another coin when the difficutly goes up (so coin return goes down).
Saying that the Monero almost price double means that it's way more valuable to mine Monero than Ethereum on AMD cards at the moment so if the AMD guys start mining Monero like they should then Ethereum difficulty could actually drop and help out the 1070 mining Ethereum.
