I have an HD 5800 card and have currently installed the Crimson 15.30.1025.1001 video driver. I believe this was the last video driver that will be available for my card. That being said, I keep getting notifications that I need to download and install the latest video driver 16.15.2211.160321a. When I go to download and install, I get a message that I currently have the most recent driver for my system. So my question is, do I really have the latest driver or not? Thanks for your help.
