currently the evga is still efficient when it comes to mining equihash as stated in the video. 4.7sols/watt is the best settings overall.
i think there are 1070ti cards out there that can top this 4.7 sols. it's just that no one is experimenting / tinkering their 1070tis. how sad.
i hope there would be another alternative to evga. they're overpriced as of the moment.
