to expensive for now, i prefer gtx 1070Ti less power consumsion but still power full for mining, since many coin show up its make me confuse choose coin for more profitable
The best ROI is 1060(3Gb) the most powerful - 1080ti, the most optimal - 1070. 1070ti and 1060(6Gb) never were the best choice for mining. Choose your own optimal option. Nowdays is not the best time to buy new cards, profit is too small but there are many used GPU that cost nice.
there are more and more coins mineable by ASIC. So be careful when buying GPU.
