NVIDIA Cards : 1060, 1070,1070ti, 1080, 1080ti.
Seriously?

Suggesting 1080 and 1080 Ti for an ETH rig is a bad advice. I mean, I get it that you wrote how they're better for equihash, but still, the thread is about mining ETH, and these two obviously don't belong to an ETH rig.
Out of all nvidia cards, the only two that make sense for ETH mining are 1060 and 1070. And 1060 is a risky buy considering how they can come with either samsung or micron or hynix memory chips, and the latter is no good.
