I've got the 1st gen 2.0ghz Macbook with 1gb of ram. I recently upgraded to a 200 gig 4200 rpm hard drive. It was a great deal and the speed is really not a factor for me. Having the extra space is great. Now I'm looking to upgrade the ram. It currently has 2x512mb sticks. Will upgrading to 2x1gb sticks (the max that this comp can handle) give a significant boost in performance? Or should I get a faster hard drive? I could probably do 1 of these 2 upgrades, but not both considering I've already bought one new hard drive. Most of my work on the computer is word processing, Keynote presentations, music, and movies. I do some Garageband recording also but no heavy graphics work. Appreciate the input!
