Upgrade a late 2008 unibody 15'' from 2.4GHz to 2.66Ghz

For context, my logic board died (overheated after installing a new hard drive). It was a 2.4Ghz version of late 2008 unibody 15'' Macbook Pro.

I finally decided to repair it as you can find logic board for about $250 on ebay now and the one I'm looking at is a 2.66GHz logic board. It really looks exactly the same, from a shape a connector stand point so I was wondering if I could just "upgrade" to this new logic board.

Thanks
