it seems to me not so much profitable.
Zcash 24 our 380 h/s = $15.45
ETH 24 our 350 mh/s = $26.39
ETHC 24 our 350 mh/s = $24.03
if for cards 470 480 380x 390x do not get to 100 h / s to not see well card

How you are getting 350mh on ETH and 380h/s with ZCASH? I am getting 400h/s zcash and only 200mh at ETH? With what miner are you mining ETH?
