Hey all, I recently bought my brand new MPB and things are going great, but within the last week I have started to do a lot more video editing and things are starting to get a bit choppy (AND HOT!). I make a habit of running iMovie with nothing else running. Its not intolerable by any stretch, but I am always looking to streamline things so my question is, If I upgrade to 4 gigs of RAM (currently at 2 gigs) from OWC, will it increase performance a great deal? Or am I at the mercy of my graphics card on this one? Also, if I have multiple questions that are only semi-related, what is the proper protocol in these forums? Ask them as separate threads or combine them into one?
