I also have a gtx 770 classified and I have not had any issues playing this game with that card. But with that said I also want to upgrade to a new card. From my research and the fact that I want to start gaming at 4k, I am going to wait until the 1080ti comes out. Everyone that I know with an AMD card says that it's ok and that if they had the funds they would have went AMD. So if your only reason for choosing AMD is for trying something different, I suggest you take another look at Nvidia. If money is an issue, I hear that the GTX 1070s perform nicely.
