I am trying to decide between which 15" rMBP to purchase. I am an iOS developer so a majority of my work is done in Photoshop CS6 and Xcode. I also watch 720p movies or tv shows on my computer. I have a 27" Thunderbolt display that I will connect the rMBP too when stationary. My question is whether or not it is worth it to buy the rMBP with the Nvidia 750M or just stick with the Intel iris pro graphics based on my activities. I want the 720p video to run great on the big 27" display as well as have Photoshop and Xcode run fine.
