I am a firm believer in using AMD chips when I make my own PC. The prices can't really be beat. My primary computer uses Intel but it was an HP I got on the cheap form Buy.com. I just built my sons a PC using an AMD chip, and have built several PC's in the past with them. AMD has always struggled with Intel and now it turns out that even Apple and Intel colluded. This only harms the computer business in the long run as having competition only helps.
