optiminer 1.4.0 card 5 - r9 390 -1755 h/s 
Hey, I just realized I have an R9 390 in one of my boxes! I swung all my Ethereum miners over to Zcash because I reran the profitability numbers on Coinwarz and figured it was the thing to do.
So with Claymore 11.1 on Linux on a stock R9 390 I'm getting 345 H/s before dev fees. Pretty close to the Optiminer number because 5x 345 would be 1725
my 390 are ~365 H/s and my 290x are ~340 H/s in optiminer, stock bios and overclocked.
