A GTX 880M is NOT a GTX8
60M. Where are you getting that the laptop I showed was an 860? Copied and pasted directly from the listings:

As far as RAM goes, anything over 16GB is overkill anyway, so it really doesn't matter. GPU is a huge contributor to game performance though
Oh and you are right about the processors being different. I actually wasn't aware there was an MQ and an HQ.
