Hello, about a month ago I purchased a Powercolor Red Dragon RX 580 4GB. I've been using it at stock speeds in my PC, but about a day ago, I turned it on and the 580 started articacting badly on the desktop. Naturally, I DDU'd it and re-installed stable drivers to no avail. I decided to give the card a full cleaning and that didn't help either. The card seems to function normally, getting normal temps in afterburner, and even overclocking than getting a better framerate, however the artifacting is so bad, it makes the game unplayable. I also can't RMA it because I purchased it on eBay, and that voids the Powercolor RMA process. So if there's a component on these cards that is known for breaking, that I can order and re-solder onto the card, or some other software issue I can fix, please tell me. I've tried just about everything I could think of.
