I have the 2010 27 inch quad core i5 imac... it has 4gb ram and 1tb. I was PLANNING to get an upgrade to 12 gb or an ssd. Is the new high end 27inch model worth an upgrade? Im just a high school student so money is a problem for me... I do some video editing, photo editing, and a little bit of gaming on bootcamp. Not worth the upgrade? How much could I sell my current iMac for?
