Best Ethereum mining GPU [Sep 20th, 2016]
Currently, as of September 20th 2016, the best GPU for mining Ethereum is the AMD RX 480. The criteria are cost, hashrate (in MH/s) and power usage. My current top pick is the Sapphire Radeon NITRO+ RX 480 8GB model with 1342 Mhz core clock speed, for approx 27-29MH/s. At current rates this $279 card should mine about $750 USD of Ethereum a year. 4GB or 8GB? 4GB models of the RX 480 offer a lower initial cost, but resale value
