which alt coin is best shot for mining?

[HAPE]

so i want to start mining with few gpus i dont know which ones to buy, im looking at rx 570-580, is there anyone who mines and could advice what would you buy to mine? and which alt coin?

and one more question, is it better to have more gpus which less power or  1 or 2 gpu's which are very strong?

If you take a look at WhatToMine calculator it will give you the most profitable coin to mine for the GPU's you have, or, would like to get.

GPU selection would depend on the coin you want to mine, as, from my research, each GPU vendor (AMD/nVidia) has its own strengths.

I guess, when it comes to power, it depends on what you're willing to spend, more powerfull gpu's = more power draw, which could/would affect you profitability.

Have a look at the profitability calculators around and then, from there, make you decision on what hardware/coin is suited to your situation.
