I already ordered two Gigabyte 1070 G1, but I would like to know about the 1060 to see which of the two is the most efficient at mining (hash/watt)
I got two G1 1070's and I love them. I can only OC about +80 on the core because it automatically boosts to about ~1990 Mhz. It basically automatically overclocks itself for every algo without having to worry about finding the optimal OC that would work with all algos. And if I OC too much it doesn't get stuck on low power mode (405 mhz) like previous generations, it instantly recovers which is great.
At first I wanted to buy G1 1080's but those also only have 1 x 8 pin aux power inputs which is not enough for me. I mean a 5-6 card 1080 rig would pull too much from the risers - for my taste at least. I mean the G1 1070's can pull a bit over 200W at max power limit (111% which is 199W on 'paper') on their own with certain algos.
I'm also interested in the 1060's but it's just not in shops yet and will probably only start popping up terribly overpriced in a couple of weeks.
