ok, i currently have a mbp with a 150gb hd with 50gb available. it came with final cut and a boat load of other programs on it which was cool, but i'm about to add cs3 when i can decide what hd to get. now i know i need a hd upgrade quick and i want a 7200rpm which will be sweet. the question is this: will a 200gb that i have my eye on be have sufficient open space to run final cut smoothly after installing a few more programs if i use external drives to save everything to? i'm thinking it'll have about 50gb open, but is that enough? let me know, thanks.
