Hi, I'm a bit new around here... I switched to apple last september with a G3 iBook, quickly upgraded to a G4 iBook. Now I have a Macbook. My white MB 1.83 currently has 1gb of ram. I was just wondering what you guys think about the difference in performance between 1gb and say 1.5 or 2gb... which will give the most noticeable system boost? is there little noiceable difference in general system performance with basics like itunes, safari and mail running between 1 and 2gb? Sorry to ask what will seem obvious questions, no noubt, to most of you. I am aware that the integrated graphics are supposed to perform better with matched pairs, but is this a serious thing or not much of a problem? Thanks for listening!
