Which logic boards will fit my Macbook 5,1?

I am looking to upgrade my late 2008 Macbook and would like to replace the logic board instead of purchasing a new computer (I know it's expensive, and I've already upgraded to 8GB of RAM and 750GB storage). Which logic boards are compatible with my Macbook 5,1? I have a 2 GHz Intel Core 2 Duo, so I could feasibly upgrade to the 2.4 GHz late 2008 logic board, but I would like to upgrade quite a bit if possible.

Any input is greatly appreciated! 🙂
