Hello Lucko, I think it is best to use RX 470 or RX 480. The RX 470 is probably the best value for hash rate to power consumption. However, the RX 480 is a better card for gaming, but it will use more power mining. In addition, the RX 480 will have a better hash rate than the RX 470. There are plenty of videos on YouTube about these cards.
Thanks... It looks like it is according to calculator that I have now found. And with my power costs at 0.06€/KWh... But are there probelms runing it for mining?
I think you should go with the GTX 1060 cause based on power consumption like 100 watt when mining Equihash you would make about 0.06 BTC per month with this card, the cost has fallen down of the card, it works out of the box not like the RX series which you need to undervolt and edit bios etc. I am starting my own Gaming PC(mining rig) with this card.
Do you have one? What have you done with it...
