We do mostly web surfing, email, occasional documents and spreadsheets, listen to music, store family pictures, and maybe even watch a movie while camping, and would like to know if there would be any real noticeable difference between the 15" rMBP 2.0GHz, 2.3GHz, with integrated graphics? We can get a Refurbished 15" rMBP, 2.0GHz, 16GB, 512GB SSD for $2,119 , whereas a new model would be $2,309 W/ Employee Discount. A new 15"rMBP, 2.3GHz, 16GB, 512GB SSD with dedicated graphics is $2,399 W/ Employee Discount. As you can see, there isn't that much difference between the Refirb @ $2,119, and a new higher end model @ $2,399. Do movies play any better with the dedicated graphics card VS the Integrated Iris Pro? I'm thinking since there is only $280 difference, the 2.3GHz with dedicated graphics card would be more future proof? What do you guys think? Thank you.
