Hello! I´m selling my windows laptop and buying a macbook pro. Due to my budget , im stuck between: Macbook Pro 15´ late 2013 with Dual Graphics. Macbook Pro 15´2015 com Intel Iris Graphics (both with 16gb of RAM) The computer will be used to edit photos (lightroom and photoshop) , coding and some light gaming ( WoW and Hearthstone for example). I am quite undecided between the older model with graphics card or the latest model without. What do you think is worth it? Do you think I should up the budget and invest in the 2015 model with graphic or it isnt justified for my use? Thanks in advance.
