How profitable is RX580 nowadays? Let's say you are mining Monero, Ethereum, Verge.
It depends on how much hashrate you can squeeze out of your RX580, which depends on the card manufacturer (e.g. XFX or Sapphire) and, significantly, the vRAM manufacturer (e.g. Hynix or Samsung).
You can get a good idea of the profitability of individual coins by using this web site

http://whattomine.com/coinsI had the same question of Intellecual Romanticist, and now i'm wondring which of XFX or Sapphire / Hynix or samsung is better ?
An other question, is there a real difference between RX480 and RX580, and between RX 570 and RX580 ? and finally 4Go and 8go ?
Thanks
I would recommend you sapphire of course but it's impossible to know if their memories will be hynix/elpida/samsung
Anyway sapphire nitro+ are the best cards actually in my opinion
There's no difference mining between rx 580 4gb or 8gb
Rx 480 are not for sale you just don't question about that

Between rx 580 and rx 570 the difference is a bit hashrate, I prefer rx 580
