Hawaii is a total beast atm wrt to ETH mining. Without much tuning you can get above 30 MH/s (for comparisons sake: with the same, low amount of tuning, a RX580 goes to ~26 MH/s.). If you can get cheap electricity as well, you're set. Especially considering the still skyrocketing ETH rates.
Just toying around with a R9 295X2.
