I want to upgrade my graphics card from my asus desktop cm1745, with AMD A8-5500 APU processor with HD 7560D Graphics card. I want to be able to play the newer games like Dark Souls 2 and Dying Light. I saw on Amazon that the R7 290 only cost $180 is that compatible with my computer, is it too big, any other ideas on graphics cards that are $200 or under that can run these kind of games and newer games that will come out. Thank You so much, dont really know much about how graphics cards work
