new macbook pro final cut editing

[jamesrickards]

Hey all ..Im looking to buy a mac to do some video editing and do some crazy stuff with motion (logo's blowing up etc)

So which one should i go for?

I thought maybe the lowest priced MBP and with the rest of my cash get a 20' cinema display/?

or should i put all my money into the better 15" MBP (i dont need a 17' version!)

Thanks in advanced - im looking only to do video editing !
