In terms of efficiency, that is hashrate per kilowatt-hour, which GPU is the best?
Has anyone tried the new Radeon RX Vega 64?
Haven't done any mining but I might invest some on a mining rig although I might mine an altcoin and not bitcoin.
It depend on which algo, but I will vote for NVidia GTX1080ti

Though I do not have any AMD card so it hard to judge them for me
