I'd go for the i7, but for RAM (to save some money) maybe a single 16G 2666 MHz to mix with the Apple 8GB which gives you 24GB total. You save the $140 (approx) for when the price of the 16GB or 32GB chip comes down - then slip it into the Apple 8GB's slot.
If that works out and 32GB chip comes down to $140 then ya got a 48GB machine.
Only argument for that route is if 24GB is not enough for now.
I may not be understanding if mixing sizes could cause a problem.
