Seems like Nvidia's new GPU mining video card will have the same hashrates as their gaming counterpart. In this article they tested the mining only gtx1060 gpu and it reached the same stock hashrates with better OC performance. I think we can say at this point the hashrate performance is dissapointing and having no gaming purpose, it will be hard to resell this card later on. The price is yet to be released but for the home miner, so far this is not appearing to be a great option.
