Hello, I am trying to help my aunt look for a new mac. She is a graphic design "artist" and right now has a G4 (not sure what that really is due to previous generations). I am wondering which mac she would benefit from. We do not have enough for a mac pro unfortunately, so it really is between the iMacs. I do not want something that could be overkill but I know this work is computer intensive. Hope this makes sense and I don't sound TOO stupid but any help is appreciated. Thanks again !
