hello, this is my first post in this forum so bear with me. i'm about to purchase the new 27" iMac i5-quad core w/ 4gd ram. i can upgrade the on a later date. mainly use of computer will be light video editing and photo editing, web browsing and some word and excel processing. do you think the i5-quad core is an overkill? for now i'm only planning to use iPhoto and iMovie until i become familiar with Mac then move to Aperture and Final Cut. my other question is...should i wait to buy the iMac until the new iLife 11 comes out? rumors said iLife '11 will come out on Aug 17th? right now if i buy the iMac it will only come with the iLife 09. i just don't want to pay extra to buy the upgrade iLife if i buy the Imac now. thanks.
