I realize that this is an older post with a "Solved" question, but feel that the question is not really "solved".
I do have personal experience with using the AMD Radeon RX 480 video card on a new DELL XPS computer & Windows 10 PRO OS. I use the Autodesk Building Design Suite Premium along with SketchUP PRO. The video card appears to have no problem with REVIT and SketchUP. They operate without issue. AutoCAD and ACA occasionally get strange "ghosts" or "artifacts" as I call them in a drawing that will disappear when I to a RegenAll, but they soon reappear. I also experience an annoying flicker on the left and right of my main video screen (I use 3 monitors) whenever I ARRAYEDIT or edit a block in place. This "flicker" does not go away until I close and restart AutoCAD/ACA. I have played with the "Graphics Performance" settings in "Options" and even with Hardware acceleration turned off, the "Flicker" still occurs. I also get strange unexplained crashes on occasion and I.T. says it is because I am not using an Autodesk "Certified" video card. Whether this is true or not, I cannot say, but I do have experience trying video cards that were not acceptable for CADD use and they did not act like this card. I'm inclined to say these crashes are caused by something else. I am using older flat screen monitors. They work just fine for everything else. It may be a subject for further homework later.
If you can live with the "ghosts" and "flicker" and closing AutoCAD/ACA when you can't stand it any longer, the RX 480 video card an acceptable card until you can find something better - or work only in REVIT. Its a shame, because the RX 480's specs look really good and with 8MB of RAM it holds such promise. Now if only AMD will write a proper driver for use with AutoCAD/ACA it would be a real keeper.
