Great, thank's to everyone for the info.
To summarize:
AMD RX 560: 0.50 MH/s
Nvidia 1050: 1.28 MH/s
Nvidia 1060: 2.25 MH/s
Nvidia 1070: 3.62 MH/s
Nvidia 1080TI: 5.60 MH/s
So Nvidia has more effective than AMD on hashrate mining. I have just ordered AMD RX 470 FXF. Dont know mine exactly. What a shame!
nvidia is better on all algorithms except ethash and equihash. For AMD Radeon owners I would recommend to mine some ethash coin, sell it and after that buy XLR or anything that you want to invest
Like your recommendation. Thank you. By the way, which coin name should I mine first? Can you introduce me some?
