AMD seems to be running some sort of promotion where if you have a Phenom CPU you can download some free software.
Quote – Experience the full force of AMD. Receive additional movie or photo editing software with a purchase of any AMD PhenomTM processor. Edit your movie or photo collection with the Serif editing software. Don’t just play, become the director of your digital life!
It appears you have to input the serial number on your cpu, so hopefully you still have the box lying around somewhere or you’re gonna have to pop off your heat sink to get it. You might be able to get the cpu serial number with a program like CPUID, but im not sure.
