I have a 750gb harddrive installed and after taking it apart I realized i can get 4gb of ram, other than that what else can I buy to make it faster/ more efficient?
That's about it - memory. Unless of course you would like to swap out that 750GB hard drive for a SSD. I also have a 2008 MacBook (the model right before yours) and added memory and a larger hard drive. I have no intention of spending any more dollars on a machine that's going on 4 years old.
