I just built my first "gaming" computer, and don't know how to update the drivers on my new GPU. Its a xfx R 7870. The help is greatly appreciated.
Drivers for that video card are here http://support.amd.com/en-us/download/desktop?os=Windows%207%20-%2064
If you installed the drivers off the disc remove them first with this http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx
