Yup, it's another gear discussion, but this time we're talking processing power! Currently i'm using my 2.5Ghz 13" Macbook Pro with the Intel HD4000 w/ 16GB Ram and 500GB SSD. For standard photoshop and lightroom it kicks butt. But, for any big photoshop files or creating Timelapses in After Effects it's dreadful. I'm contemplating selling and upgrading to the Mac Daddy 15" Retina w/ discrete graphics. For only a few hundred extra it seems like the logical choice as discrete should have more processing power. Thoughts? Have any of you had this same debate and how'd you lane?
