I have a mid 2014 rMBP 15', base model. Therefore it has Iris Pro graphics, 16GB RAM, 256GB SSD and a Quad 2.2 GHz i7. I am currently using Bootcamp to dual boot Windows 8.1, and am wondering if I should buy GTA 5 on Steam. Will it be able to achieve medium-level graphics at a stable 30 FPS? What about resolution? I currently own the X360 and XOne versions of the game, and the reason I want to get it on my MBP is so I can game while travelling etc. GTA 5 is my favourite game and basically the only game I play nowadays. Please let me know what I can expect and how the game will perform in comparison to the two Xbox versions!
