I am one of the most experienced mining with that specific card here. To make a long story short:

"Only mine Zcash with it, through EBWF Cuda Miner or Nicehash"

Personally I am using Nicehash and I am very happy with the results, 0.0012-0.0015 btc per day.

It is also good for Eth mining, of course it cannot be compared with the RX series, but it can do 19 Mhash if you are one that thinks price of Ethereum will go higher and higher.
