What I am hoping is it helps improve performance but I am thinking only if I run a lot of apps at once. The areas I see sluggishness are in iTunes, Aperture 3, iMovie and iPhoto. It is not unusable by any means, but more beachball action than I like. Are these programs only really improved by a better processor? Will RAM help if I am not running lot of apps at once? Thanks!
