You don't have to wait for somebody to post instructions as to how to download the 12.8 drivers from the AMD site.
You just go to the AMD support page and "follow the wizard". You can fill in the blanks manually, or you can let that page "auto-detect your hardware".
Or, you can go to the dedicated "sticky" thread for the latest AMD driver at the top of this "Graphic Cards" sub-forum on SevenForums, which will lead you to the same place via the download link on that first post in the thread.
If you've never updated a graphics driver before now, you're about to learn how. Once again, I recommend strongly that you first take a "precautionary system image backup" that you can quickly restore from JUST IN CASE if the driver update process fails or is a disaster, and you cannot get back to your current setup easily.
Otherwise, you should probably be able to just run the Catalyst 12.8 installer right over your current setup, and everything should complete without a hitch. Re-boot, and you're now on 12.8.
