Logic Board compatibility upgrade

I have a Mid-2012 MacBook Pro 15" A1286. 2.3GHz Processor. Most of everything works except the USB ports and Optical Drive. I took it a while back to a shop and they told me it had liquid damage on the logic board. I didn't have money then to fix it and it still runs fine. Just can't use the USB ports or Optical drive. Now I'm thinking about upgrading the RAM, it currently only has 4GB and is getting painfully slow. Is it possible to upgrade the logic board to one that has a faster processor? What would be the best way to get one? eBay? Thanks!

nice! So I could upgrade the CPU from a 2.3GHz to a 2.6GHz? Thanks Dan.

Did you click on the first URL link? These are your choices. The logic board I listed here (2.7 GHz) is the premium system logic board is a direct drop in. If you don't want to go that high you can also go with the 2.6 GHz board its P/N 661-6492

I made a small typo in the board description in my answer it's a 2.7 GHz not 2.6 GHz (i've corrected it)
