I didn't have a MacBook Pro with this chip, but I did have an HP laptop with it. After a year of use, I started having to turn it on and off multiple times in order for it to boot. A few months later, it finally died and would not turn on no matter what I did. I was still under warranty so I got the motherboard replaced, but it died again three months later. As the other poster said, it did get VERY hot within minutes of being on, but since it was my first laptop I thought that was normal...
