G51VX-RX05 CPU Upgrade - Question

Hey guys,



This very well could have been answered already in another forum, if so I appoligize I did try and search first.



With my G51Vx-RX05 (Best Buy) warantee now up and no longer good. I would like to upgrade the CPU as the whole computer bottle necks w/ it.



I cannot find any information on what motherboard I have in my laptop and was hoping someone knowledgable could either let me know what model motherboard i have or list out acceptable CPU upgrades that I can put in. The quad core would be nice, but i keep seeing mixed answers on whether or not i can move up to that, im thinking not.



Thank you!
