Any recommended makes and models of 1070's to look at? Do I understand that there is no need to go tweaking bios on the Nvidia cards to get the performance from them?
Well more like you can't mod bios because they come with a digital signature, so that need to be circumvented somehow. In the future maybe
as for model, im pretty happy with the EVGA 1070 FTW, they come with 2x8PIN connector for power, and are very stable even @ good OC (i run them @150/600 - 50-60% TDP depending on crypto) rock stable. They're not the cheapest ones that's for sure, i got them at a real bargain, even regretting not just buying more to resell them lol.
27MH on etheruem
is that on linux, because on windows 1080 could only do ~4 MH/s it seems ?

Nope, on windows10 im getting 22Mh/s with GTX 1080
i do with oc around 31mh ethereum but it's not the good crypto to mine nowaday with nvidia, zcash or monero is the way to go
I know the 1080 got issue with ethereum because of it's special memory, but a solution was found for zcash, maybe one will come for ETH when it'll become interesting to mine again ? we'll see
