Looking to upgrade my 2010 Mac Mini. I've read about all the upgrades etc the 2012 Mac Mini can do, but I don't think I need quad core or SDDs. I'm debating between: 3.0Ghz Dual Core i7 Mac Mini - $1400 27 inch iMac - 3.2Ghz Quad Core i5 - $2000 I already have 2 monitors off my old Mac Mini, but that 27 inch is nice. I never really liked the all in one package of the iMac, since if there is something wrong with the screen, you're stuck with it. BUT is the Quad core i5 THAT much faster? Main use will be Lightroom and Photoshop editing/processing of RAW files and Video editing DNx and 4K footage in Avid Media Composer. Right now my current Mac Mini cannot handle 4k video files. Will the i7 Mac Mini do this? Or is $700 a small price to pay for a quad core i5 and a 27 inch screen?
