I am a video editor and motion graphics designer and I have been researching this until my eyeballs have about fallen out of my head.... I still can't seem to find the answers I am looking for about the computer I have currently VS the 2011 Core i7 iMac. I know that there have been similar questions posted regarding this, but I have yet to find one geared towards my specific setup: I currently have a 2007 Mac Pro (desktop): 3GHz Dual-Quad Core Intel Xeon Processor 4GB RAM 1.5 TB Hard Drive ATI Radeon X1900 My questions: 1.) If I were to sell this, how much should I ask for it? 2.) Should I decide to sell it, would going to the Core i7 SSD iMac be an upgrade, downgrade, or about the same performance? 3.)I know that the Mac Pro is expandable and has more cores, but with the updated processor and new technologies built into the iMac, would it make up for it? This article from Macworld is what piqued my interest, and I am just trying to get an idea. http://www.macworld.com/article/160469/2011/06/ultimateimac2011.html Again, I know that there have been similar questions about this topic, but I need specific answers for my setup, so if you are going to bash me for re-posting a similar question, please don't bother.
