Hey this is my first post and i'm a (hopefully) soon to be switcher. So, I plan to buy either a 12in pb to use on my commute to and from school and on my 20" crt at home or save up some more money and get a dual g5. Im a student at the School of Visual Arts in manhattan and want to know what you folks running shake and after effects would recommend that i do. I have access to g5's at school but dont want to be confined to doing all my work there. my other option is to buy the pb now and save up for around this time next year to get a dual 3ghz. i just dont know how those programs will run with only 1.25 gigs of ram and motion recommends 2gigs. help a fella out
