the question is i have a pro 17' with a 2.3 ghz processor. ive been looking to getting a new logic board. the thing is that i want to get the 2.6 ghz one. the thing is i have no idea if the 2.3 and 2.6 are compatible with each other. they seem to be from what i see on the pictures given to me. so the question is it they are compatible or not?
