Well if you are using Crimson it should show up on the System's tab. Click on Software at the top or Hardware Radeon to find out.it should show it there. If you don't know for sure. There is a wheel icon at the top of the Radeon browser. Click on it. It will tell you what is compatible for your card.
But most card drivers are all similar. For some reason they're grouped into the same category an this for me has presented problems because i have older cards an i see them out perform some of the newer cards in (some categories) But they should all be the same kind.
