No not at ROI yet and hobby's cost money so i don't think it's that important. I just want to mine some btc for an other year and then save them for 10 years.
When al 5 where overclocked it took me 14 days for a btc. But one broke down du to shit bitmain softwere. (burn it self to dead) So ROI will take some time.
Ps i don't think this is the right topic for this discussion.
Alright but isn't 10 years just too long lol, but congratz for your rig i like it, i was buying a G-black to mine scrypt coins but i changed my mind. Good luck
