WyomingKnott :
Add some workstation cards to the review. If they turn out to be hashmasters, it would relieve the strain on the graphics card market.
fat chance.
A titan V would have handily crushed any of the cards here with its 70+ MH/s Eth rate.

But when it comes to making your money back you use:
Cost of graphics card / Megahashes per second (Easy to understand formula, real formula at the bottom)
For the Geforce 1060 that comes out to roughly
$400 / 25MH/s or 16 dollars per megahash (I was able to buy 4 1060s for about $300 each a few months ago. Score!!!)
For the Geforce Titan V that comes out to roughly
$5000 / 82MH/s or 61 dollars per megahash.
As you can see it would take at least 3.8 times as long for a Titan V to pay itself off, not including the power cost.
This isn't the most true comparison due to not taking power into account, but still gives an easily understandable way of seeing why a $5000 GPU isn't worth mining with.
You could have simply bought 3 Geforce 1060s and had a similar hash rate for cheaper.
The goal here being to make back the price of the graphics cards, then everything else is gravy.
Ideally I would have used the formula of
Cost of graphics card / Spreadsheet calculated monthly income taking power and other fluctuations into account.
to calculate on average how long a graphics card would take to pay itself off.
