CPU's

[PAA968 Kenny]

Hi.

I have a Dell Dimension 4600 Motherboard. This is my old motherboard that came with my computer. The motherboard had a Pentium 4 CPU 3.06GHz. I want to put this motherboard in to a Dell Dimension 1100. My plan is to take the 2.66 CPU and put it in to the 4600's motherboard. The question is, will the pins on the 2.66 fit on to the 4600's board?
