Hi ladies and gentlemen, I am looking at getting a rMBP 15" and just need some general advise on if it will be able to handle my needs.. I will be using the machine to do a fair bit of graphics work on Photoshop and a lot of C++ coding on it.. I will also be looking at playing WoW casually on the machine and will watch some movies from time to time.. As all these program's probably wouldn't fit on a SSD (I don't think?) would it be possible to run these program's off of an external HDD? What MacBook Pro would be best for me? What would be the best way to run the program's I need? Would the 15" MBP's be okay for what I need them for?
