thought I mite see more out of the 390. Seen some post higher and some the same or so..
May try a 6870 just for fun, probably have driver issues....
Seems most cards will hash on this miner. I am running on all rigs the latest AMD drivers.
Yet to test 7950's, 380 and 380x, 280x's and 290's and 480's (8gb)
All signs from previous algo's and early testing of Nicehash etc. makes it seem like 390/390x is the fastest, and 470/480 eeking out a slight advantage in Watt/Hash. If you have very cheap power, 290x is a winner on price/hash.
My 2 cent
Good, cause I am getting ready to test 3 x 290's will report back with the rest of farm in a bit
