What are best examples vegas best for mining

Solution
supposedly none? theoretically all?
Reasoning is that while Vega's could crunch a lot of numbers, 99.9% of miners are also concerned about power usage since that affects profitability a lot. and no, 300W+ is not looking pretty in there.

Vega, 30 to 35MH/s, power usage 350W,
Rx480, 25MH/s power usage 150W,

as you see, it's "better" but it also "costs" more and eats more power/hash so.. less profitable.

Solution
Since I believe that others might benefit from the reply too, I'll answer here instead of PM:

both 1080 and 1080 Ti are uneconomical due to high card cost and not much bigger mining speed than other cards.
https://bitcointalk.org/index.php?topic=2089171.0

as you can see, 1080 is slower at mining than 570, 480, 680, 1070 or 390
while 1080 Ti is faster, it also costs enough that you can usually get TWO other cards at same price and thus.. get more mining speed for same cost.

so.. things to consider with mining:
Card mining speed
Card power draw
Card cost

and remember, value of crypto currencies fluctuate a LOT, possibly making now profitable setup unprofitable next week. (electricity costs more than you gain in crypto currency)
