I am upgrading from a Mid-2010 MBP, and will be using programs like Photoshop, Cinema 4D and Maya, as well as graphics intensive games and Bootcamp. I am planning to buy the high-spec tier, but should I get the i7 configuration? Will it make much of a difference with what I use it for? Also should I get a 16-GB RAM Upgrade? I currently have 16Gb RAM on my 2010MBP, along with a 1TB SSDHD Hybrid.
