Just out of curiosity, would upgrading my laptop from 4gb ddr2 667 to 4gb ddr2 800 be worth $40? My laptop is not slow by any means but for $40 I thought it would be worth at least asking. According to the Vista performance index my RAM is the weakest link in my system with only a 5.1 score. The only things I do that require memory are the occasional game (most demanding of which is TF2) and photo editing. So, worth it or not really?
