Over the years I've had AMD and Intel machines. I could go into details but that won't be necessary. The bottom line for me has been satisfaction with Intel, and annoyance and dissatisfaction with AMD. Everytime I bought/upgraded to Intel hardware it felt like an upgrade for a long while. The honeymoon with AMD hardware has usually ended about a week after the change. It could be bad luck, but I've never been so satisfied with a piece of computer hardware than I am with the Core 2 Duo Processor. It just seems like AMD takes their cues from Intel and are always a step behind. That's my feeling ;p
