Has got to be 390. My 390 slightly overclocked is getting 290~sols/s with v8.0 i4.
or 2*380

it is 390, sry about the typo
what numbers to set for "easy" OC that doesnt cut into card lifespan much?
btw, I was thinking about getting another one, but my psu doesnt have anymore connectors. R9 390 uses 2x 8 pin. I believe my psu can handle the load, its 850W, but it doesnt have any more 8 pin connectors...
Is there any adaptors molex-> 8pin? Or something like that?
