If you are looking for a cheaper card with high hash rate and dont care about consumption I would look into the AMD R9 Fury (original fury not the X). Out of the box it does 450 sols just like a 1070 and you can find them for under $300 if you snoop around enough.
Thanks for the suggestion haha. I think I'll stick with nvidia tho, always preferred their products. And holy hell just looked it up, that R9 Fury pulls 400 watts fuuck. not worried about the consumption just would rather not have to spend a grand on power supplies to hook those bitches up lol. I dont think Ill be picking up any more older cards, and will likely wait til the next gen launch of nvidia cards before deciding what new cards to get.
