Im in a dilemma whether to go for Retina 15 Early 2013 or Late 2013 ? Early 2013 one has dedicated Nvidia 650M, while the Late 2013 has Intel Iris Graphics. Im not sure, which is best and which is effective. I mostly do short fullHD movies on Premiere Pro and work with after effects or photoshop. Thats all. Let me know, what would you suggest.
