All RX580 320€ are sold out now. There is a still possibility to get RX470 8gb, GTX 1070 and GTX 1060 6GB. Gainward 1060 6GB good option for 270 - 20%? I think I would go 7 of them. 1070 is good choice but 4 cards are not enough to mine ethereum. If 7* 1060 makes ~ 140-170? And I can also mine Zcash if etherum is too hard to earn.
