Re: 1080Ti Specific - Best mining option

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.

Not everything revolves around Ethereum. In everything but Ethash 1070 Ti is the best all-round card for price/performance because on hash/price it costs as much as 1060 3GB while occupying only 1 slot.

Try to read the whole answer. So, i dont now why you decided to speak about eth. And even without ethash(if you so like it) - it`s one of the most useless cards for mining. Classic 1070 gives you hash about 1070ti with all algo, but costs 1.5 times cheaper. Try to count, to read and to think before answering.

No, 1070 Ti doesn't cost 50% more and surely doesn't hash as much as plain 1070. I don't know where you get your numbers from, but the difference in Europe is around 20-50 (~10%) while the hashrate on most algorithms scales linearly with CUDA core count (~25%).
Do your research before speaking blindly, you are embarrassing yourself.
