"If you are unhappy with your ATI graphics card and the performance delivers in recently released games, there’s a good chance that the manufacturer’s latest driver update may fix this issue. Performance increases for certain games are what we are expecting by now from driver updates, but version 7.10 certainly is a standout."
That's the point. It's for driver compatibility with newer games. Sadly, I still can't play Jade Empire SE with Anti-Aliasing because of a driver incompatibility with my Radeon X850 Pro.... :-(
