I'm running a Revision A, entry model 1.83GHz Core Duo MacBook with a 60GB Hard Drive (soon replaced) and 512MB of RAM. For doing daily tasks like email, web-surfing, Word proccesing, Photo editing (nothing big just iPhoto), Listening to music,... I find my MacBook beachballing a lot, and heating up quite a bit too. So how much RAM should I install in my MacBook?? Should I Max it out at 2GB??? Should I replace 512 for 1GB?? Would do you recommend?
