Wow, with such a cheap price, this kills everyone. At low projected return by March, 2x GPU is a alot better and more efficient, 300 watts vs 1300 watts AntHeater A3 (assuming both may have equitable net yield by March 2018)...
Idk bout that, $1200 for two rx gpus that the real price is $280 so you are paying
$600 plus more that they are worth.
A3 is a better buy
but the best option is neither
