I've always used Nvidia graphics cards until now. I recently upgraded my 6 year old 8800 gt to a r9 270, a long overdue upgrade I know.... With Nvidia it was always super easy to get my drivers. Their website would tell me exactly what driver to get after scanning my system and seeing what gpu I had. I went to amd's website and downloaded a driver that seems to be working fine. But one of my programs didn't recognize my driver and says I don't have a certified driver. My gpu was made by gigabyte. If anybody can tell me where to get my driver and which one I would really appreciate it. Thanks
