Hello! I have decided to make a little upgrade and after a few hours of research I reached at the conclusion that the Sapphire Radeon Tri-X OC R9 280x is the best for me. I just placed the order and after did a little more research and found out about this artifacts problem which, I think it's very annoying so, the question: Is this a problem that all these gpus have or it depends on your luck? It's very important for me to know because if all of them have this problem I still have time to cancel the order. Thanks for help!
