I just bought the rx 460 4gb for $109 today, mining GRS at 8.35 mh.
could i have done better for price? I can still return it.
EDIT: also my electricity is $ 0.02534200 per kw/h
Next time, go for RX 470 or 480. These two are the best, you would have been getting a good hashrate with these two.
RX 460s are not good at all in mining.
But hey, you've very cheap electricity!
