I have a p4 1.7ghz and a p4 2.4 One is in a dimension 4300, the other in a dimension 4500. Do those pc's have the same mobo socket and chipset? How would i check such a thing. I apologize for being ignorant to this. The reason I ask is because I am considering buying a higher end AGP video card, and I want to be the least cpu limited as possible. Thanks
