Hi there, I have a Sapphire Radeon 7790 OC 1 GB graphics card and sometime next week I'll be getting the Sapphire R9 270X(the tripple x toxic fan version) and I was wondering what do I do with my current drivers when I get the card? Do I uninstall my current drivers and install the default driver for the 270x then update to the newest version of the driver? Or do I keep the current driver since it's already one of the most recent from AMD? I currently have the 13.9 driver version.
