TBH I'm getting a little bored of the X GPU is better than Y GPU cos Avg's...the RX cards are under valued, the 580 can run most if not all game at ultra setting 1080.
It's not that simple and simplifying it like that is literally fake news (sorry HWU you are fake news!!!). Buying the right card for usage is more important. For instance if you need RTX for one of the 3 games that use it, it becomes a selling point. If you play a lot of iRacing then GPU choice is only really a factor after CPU choice. Even then both camps give similar results with similar performance brackets...
It's not a straight X GPU beats Y GPU, it's always something to tailor to ones needs. However people do go overboard with 480p PUBG at times so yeah...
