Pentium 4 switching Help!!! I have a Dell 2400. It has a Pentium 4 2.8Ghz. processor. I would like to know if I will be able to switch over my processor over to a new motherboard perhaps containing a PCI-E or AGP slot available. I am unsure of my CPU Socket. I have the Dell specs about my computer here: http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/specs.htm It would save my a lot of money if I am able to switch over my processor into a new motherboard! Thank you very much!
