Radeon 560 vs Radeon 555 Planning to buy Macbook Pro 15 2017 model. Is there a big difference between Radeon 560 and Radeon 555. Which should I go with? To give you background, what I shall be mostly using my MBP for: 


Lot of editing in Photoshop/Photos
Quite a lot of Applications being opened (nothing graphical though - Skype with Screen Sharing, Chrome with 100s of tabs)
Playing and editing Videos
Virtual Machine for Windows running in parallel
Dockers shall be running
Vagrant shall be running
Sublime Text with 8 or 9 projects being opened
Xcode
Android Emulator
Multiple external monitors


What should I choose?
Looks like the 560 massively outperforms the 555 in benchmark testing:

And looks like it has twice the VRAM (4 Gb vs 2 Gb) which to me makes it a pretty easy decision.
FWIW - I'm a graphically-intensive applications user, and having a GPU with more VRAM means better performance from apps which target GPU processing, so I'm not a typical use-case.
