In my experience, Intel's have been much more reliable and problem free. And if combined with an Intel Original MoBo, you don't have to touch the system for years.....The insides of my system were so dusty when I performed a clean up, but the system runs magically.
AMD on the other hand is a good performance CPU, very fast and all, but it screws up in the end. (all this, in my experience). I've had so many problems with the two AMD systems, my friend has had problems with his AMD system. From now on, it is Intel or the highway...
