intel mobo 915 or 945

i am interested in a mobo upgrade to either a 915 or 945 intel board.
can any of you guys give an informed analysis re the above.
i am not looking for a dual core board but 64 bit and the pci express and agp option would be a requirement.
also dependability is a strong requirement are these board clockable??
thanks for the info
