Ok so ive been doing alot of work on my macbook pro. I installed a 500gig hard drive and 4 gigs of ram. Now can I upgrade my intel chip? I preferably would want to upgrade it to a quad core, if i do that, do i need a new logic board? And if so what one? If not that I would want to give it a faster core 2 duo, is any of this possible,a and if so, how? PM with answer or reply here, thanks!!
