I went to three local PC repair shops, and they all acted weird when they saw my RX 470 (Mining Edition)! They completely refused to help, because it it is Bitcoin mining card and they don't repair such a hardware. But all I wanted was to test if any different PC recognizes GPU as device. Simple and easy don't see much difference from regular RX 470. They acted like I am doing something that is not allowed... Are GPU mining illegal? Why they refused to help?
So here is the full story of my RX470 problem: https://forum.ethereum.org/discussion/17511/weird-problem-rx-470-help#latest
