Hey guys, I'm deciding between the new 6 and 8 core Macbook Pro 15". I do a lot of video editing and Photoshop. I'd love to get the new 8 core... but I heard that of all Macbooks the higher end model always devalues the most once you buy it. I upgrade and resell my Macbook Pro every 3 or so years so I want to get the model that will get me the best bang for the buck. Would I be OK getting the 8 core and re-selling it later on? Or wiser to sacrificee some performance and get 6 core?
