Hi I'm newbie and first post here. I'm sorry if anything goes wrong with me 
I read articles about AMD GPU mining if we using $300+ 6 AMD cards we can get 4kH/s speed and it can earn nearly 150$ per month. Maybe I'm wrong.
Then Zcash Its more difficult to generate hashes, I think. If we use above mentioned 6 AMD cards there is no profit.
Please tell me am I wrong or correct?
Thank you!
