AMD has released a small hotfix for its Radeon graphics cards that corrects an issue with the HD 4850 X2 and 4870 X2. As their names suggest, both products feature a dual-GPU design, but it seems they weren't being properly utilized. The company doesn't really say how much of a performance gain you'll see by applying the update, but it's probably worth downloading if you own one of the aforementioned cards.

The Catalyst 10.8b hotfix also adds the ability to force anisotropic filtering in Tom Clancy's H.A.W.X. through the ATI Catalyst Control Center. That change affects all DirectX 10 products (Radeon HD 3000, 4000 and 5000 series), as well as Windows Vista and 7. Windows XP users need not apply, apparently.

Since this is just a minor update between the "real" driver releases, AMD notes that it hasn't been through extensive testing and it's provided "as is" with no support. If that doesn't scare you off, you can download Catalyst 10.8b here.
