Oh well one thing more then, in CCC, make sure you do 2 things in the ATI Overdrive window. First is to "unlock" the card just by clicking on the lock icon. Second is make sure you have the Enable ATI Overdrive checkbox UNchecked. If it's checked, it's probably overriding Afterburner. If all that fails, and you still want to OC, you can BIOS flash them. There's plenty of BIOSes available just make sure to google some guides first.
