I currently have a 2010 27" iMac: 2.93 GHz i7 12GBs ram 256 GB SSD (O/S and programs) 2TB hard drive (storage) all work was done by Apple authorized third party store and Apple Care is good until August of this year (I bought this new in 2011 from MacMall after Sandy Bridge iMacs came out). I have the option of selling now on eBay and upgrading to top of the line 2013 model or waiting. If I wait there won't be any Apple Care when I sell the 2010 iMac but in theory I will have a newer/faster/better iMac than current models. The question is how much better than the current version and is it worth waiting? I use FCP, Aperture and Photoshop a fair amount. I also use Quicktime Pro to create time lapse videos. I'm not concerned about Thunderbolt 2. I would appreciate any and all opinions on this. One last question. What comes after Broadwell and what if any knowledge is known about that generation of CPUs?
