Upgrade Dell XPS 420 motherboard

Hello, I've recently come into possession of a dell XPS 420, as I understand it's about 5 or so years old, I was curious as to wether or not I could upgrade my motherboard from a dual core to a quad core, I don't mind having to change power supply and everything else, as I was planning to do it anyway.

Any help or information would be greatly appreciated.

Thank you for your time and help.
