Getting more RAM into my book?

[ltHank]

I'm using a MacBookPro3,1 and am aware that it has a 64 bit processor. I currently have the stock 2GB of RAM in my book, and I was wondering if it is feasible for me to upgrade my book to have more - and would I really get benefits?

Possibly a stupid question, but I am not really used to messing around with my MacBook. Will it be able to use all the extra memory? Will it take full advantage of the 64 bit?

EDIT:: Just wanted to add the reason I am posting is that I am still somewhat confused by the above posted link about RAM.

more is always better. you may only notice a difference in certain tasks though. when i went from 2 to 4, i noticed my wake from sleep time was cut in half and after the initial start of programs, they all started much faster. as cheap as ram is right now, i would max out any laptop i had.

Cool, that is what I was hoping to hear!
