I tip my hat to you sir. Done some more reading and you are right. 580 is match for 1060 6gb on DX11 and better value for DX12. Power consumption is the drawback but it is valid option.
£309.65 expired? I just paid £225 for a used RX 580 8GB, the guys ebay history didn't suggest he had been mining on it.
True. I like digital foundry a lot though! Very in depth!

Best priced 8GB 580 in a long time!
