So I was about to purchase a refurb 27" 3.06ghz duo core, replacing a our older 20" iMac 2.44 ghz, just when these new ones Core's show up. Is the price difference worth it. let's face it, less than a year ago, these 27" were the best thing next to slice bread, how much of a time saving performance saving will it be for occasional taking work home (some photoshop), but mostly as a home photo, video and surfing around computer. with a price tag of $1449 with 1TB, decent ATI 4670 over the entry $1699 i3 price tag of the new models? Based on the above, Go for the refurb or spend evan more?
