R9 series (possible) fixes
I used to have an R9 290 I got used for a great price. Tried to use it, and it kept black screening. I read the same thing about a lot of other 290's and feared the worst. However i had a aio liquid witha the kraken g10 lying around from attempting to fix a dead 7950. I stuck on, and sure enough it cured the system. That was 3 years ago, and I gave it to my brother. He still maxes out all games, with no issues. Might fix a broken R9 280 is what Im thinking.
