I don't think at all :)
With latest versions of NiceHash miner my GPU started mining as well. Net outcome is around Euro per day. No, I didn't calculate the cost yet.
I will do that after the next payout that will be on Friday.
A question - how do you mine anything besides bitcoin with Windows client?
for ZDASH I used the Claymore binaries. ( Nicehash uses them too )
Claymore's ZCash AMD GPU Miner v12.4
You need to make a .bat file and put you settings (pool, worker, pw) there.
I should write a short guide :)
Do that :)
It will be very popular.
Found a guide on Steemit :) :
