I don't know why but my R9 280x is reading as a Intel HD Graphics 4600. Also I can't play high end games which is weird. I tried to play the new Rainbow Six Siege but I couldn't play it above 10 FPS. Then I went to change my settings, oddly it said that my graphics card was a Intel HD Graphics 4600 ( In the game settings). So then I went to check what it said in DxDiag. What do ya know, it says Intel HD Graphics 4600. Also I don't know if this has to do with this, but Rainbow Six Siege is taking up 4 gb of ram. I just got the R9 280x and put it in today.
