The guys from
Chilehardware have managed to get their hands on the leaked AMD Overdrive 2.11 beta.
The new Overdrive checks for the system specs when installed, so those that have Intel, VIA, Nvidia, or any other chipset shouldn't bother to install it. It works only with AMD 7xx series, but if it can squeeze additional overclock from that Phenom CPU, it's worth a try.
