If you buy an Athlon XP 1800+ 1.53GHz chip OEM, they offer a dealer warranty anywhere from 15 to 60 days. If you buy Retail Box they advertise a 3 year warranty. Does that mean that if you buy OEM and your CPU dies after 3 months that you are out the money spent to purchase the CPU? Also what is the difference between an OEM and Retail Box except, the box? I'm sure some of you have purchased an OEM at some time or another. Thanks in advance.
