Debating getting a new Imac 24 in or a Mac Mini and buying an inexpensive TN 24 inch monitor. I mostly use it for Garageband and some limited video editing, got a new flip hd camera. Curious if the additional performance is needed for basic movie editing and garageband. Only other performance related stuff is ripping movies- which takes forever on my current imac g5. Love to hear people's thoughts- obviously would get the imac if cost were no option, but thinking of using the price difference on music gear. Would love everyone's .02 on the potential imac refresh as well. Thanks.
