Re: What are the best replacement for RX 480 / 470s for Ether Mining?

You need to wait about 2-3 weeks to be again in stock.
1060 has lower hashes, 23-24MH/s I think look at benchmarks, but better power consumption.
The problem I have with the 1060s I bought is that some have Hynix RAM and others have Samsung RAM.
Samsung RAM 1060s I am getting 23 MH/s at about 65 - 75Watt per card.
Hynix RAM 1060s I can only get up to 18/19MH/s at like 80Watt per card.
And you have no idea which version of RAM you are going to get.
