Hi all. I'm going to get my iMac next week. Well, the thing is I will use it for photo editing, gaming... I can get the new iMac 21.5" i3 or i5 or for the same price of the 21,5" i5, a refurb of the 27" i5 Quad-Core, with the 4850. I want the machine to stands at least for 4 years. I know that it won't be able to run games in some years, but it happen with every computer.
