Hi guys, i've been reading through these forums for a while, not actually contributing, but i was hoping i could get some help with a little situation i have. i have a hand-me-down macbook pro core duo 1.83 ghz from early 2007. i was wondering what would be the best possible upgrade i could do to this machine. i know ram and hard drive are the obvious suggestions, but with a pretty damaged logic board the machine runs a little slower than it should. what do you guys think? the fans definitely need replaced. thanks for any help guys.
