I just got an AMD XP2500+ the other day but today I visited a store and decided to ask the guy there which was better and why. He said "The Pentium is better" no red flag so far but then he proceeded to tell me that the life of an AMD was 1-2 years, after that they die because they run hot. A red flag went up. BTW, I only saw Pentium processor in that store. So what's the deal here with the AMD. Any truth to his claims? To answer the original question which do you think is better and why?
