Summary: It is a very good processor, my original was only a 4200 processor. The 5200 is a bit more functionable but not much.I am working with an AM2 socket so I cannot go much higher. I am learning though and I believe that I may be able to go with a 4 core. This processor is great.
Summary: Great upgrade for my Compaq/HP computer and this is the upper limit that it will take on my motherboard. You must get a better heat-sink and fan for this CPU. It may run hot with a small slow fan and sink.
