Well, first off i have a 2 ghz intel duo processor 2gb ram 13inches 120gb hd

lately i have been using a lot of video editing programs, as well as parallels for a few things. my computer is definitely going slow b/c i don't have enough ram... if i were to just upgrade my macbook i would be adding max ram as well as the biggest hd i could afford. how much Ram could my macbook handle?

would it be worth my money to just get a new MCP b/c my processor is 2.0? maybe a 2.6 or 2.4.. is it worth the extra money? i know there are other features with the MCP but i'm mostly concerned with performance.
