I disagree about Zotac. I have MSI, ASUS, GBYTE, EVGA and ZOTAC. I like Zotac the most among them all. Rock solid build, quiet, fast. This is purely subjective I must say but still. I'm in love with Zotac.
And there's one good objective point. Zotac AE 1080 is the only card among my others that gives me totally stable 595 sols on equihash. For others 570 is an achievement, average 560.
I have only Zotac's 1080'Ti for the moment (EVGA and Asus on the way) so let's share information a little bit.
Zotac 1080 Ti AEC Edition gives me 765 sols on Equihash. What about your results?
