Hello,
now i can find 1080 at 50$ more than 1070, the prices of 1070 are really high.
I consider looking at whattomine.com 1080 has more hash in all algo.
So is really better to go for 1080 instead 1070 ?
What about KHash/W ?
What about stability are a 1080 rig stable ?
With signatum i have around 280/299/KH/s with 1080ti and 270 with 1070.
My vote would go to 1070 as well. While 1080ti is a killer for Signatum. Sigt will be going POS soon so keep that in mind.
Why your vote is for 1070 ?
Looking at whattomine 1080 give more Hashes so it will ROI faster if it cost little less than 1070 also in other algo.
