Not sure what to do... Upgrade my macbook or buy MBP

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.

Without listing the model or year can't give you an honest answer but you can go to Crucial.com and get the info after it scans your computer and as for new yes it would do
it faster as with anything newer plus some other features such as a better trackpad and longer battery life.

lol sorry model number is A1181

Depends on what year Mac you have as to how much RAM it can utilise.
Mid 06 2GB
Late 06 3GB
Mid 07 3GB
Late 07 6GB

For the cost of RAM and a faster HD, if you are utilising the RAM like it sounds like you are, you would definitely see a performance improvement, for a lot less of a cost to getting a new Macbook Pro.

A1181 covers all Macbooks until mid 09 except for the aluminium Macbook.

umm well the production date was april of 2009

Alright... it was May 09 and you can go upto 6GB.
