Thank you all for help.
@TGJ I get between average hushrate from 84mh/s all the way to 96mh/s.
It changes every few hours constantly.
I did tweak my GPU with MSI Afterburner
Core is -120
Memory is +1000
Power limit is 70%

I had stable PC with memory overclocked up to +1080,but I had same hushrate,if not worse with it.

@FireBallex Yeah I made a mistake while writing,I know miner such as T-Rex is not responsible for payout.
Thanks for info tho.
