I have a MB core duo (not core 2 duo) I have 1.25 Gb of ram.. I upgraded one of the sticks to 1gb so they don't match. How much faster with video editing, (FCE) or other tasks will I be with 2gb? I am trying to tide myself over until new mac pros are released. Also, how comparable would my system be to a new MBP with 2GB? I have looked at barefeats already. Guesses?
