16 GIG"S man I have 2 as well and I don't think I have ever maxed it our while editing.
alright - maybe I'll stop at twelve
maybe..... for now.......
but this baby's aiming for some serious animations with numerous layers of effects etc...
The beauty with the Apple suite is that they are so well interlinked that edit software (FCP) and animation software (Motion) and Soundtrack and DVD SP et all can all be open simultaneously....
Instead of exporting a Motion project into a FCP standard, the actual saved Motion file becomes the media which is imported into FCP..... (and vice versa, all the way through the suite) as you then re-save one project, then it instantly updates in the other linked projects....... if that makes sense!?!?
generally on my present MBPs (1st gen dual-core 2.16GHz processors) if I am changing a little piece of animation in Motion this means another loooooooooong wait for a render to go through in FCP..... for maybe a 10 second clip..... (!)
running 2Gigs of 667 RAM....... the new beast takes 800MHz RAM which should also be of extreme value.....
I know that the graphics card will answer most of my woes but I still don't want to see that spinning beachball (our equivalent of the egg-timer) appearing all too often...
I'm reckoning that minimal money spent on RAM will very quickly pay for itself in previously wasted finger-twiddling time.
