Hi all. Longtime PC gamer. Relatively new Mac gamer. I was just wondering if anyone has seen any issues with prolonged gaming on a MBPR. Mine is a late 2013 model with the nvidia card. Over the course of a few hours, all games play fine. The fans come on to a noticeable noise level, but they aren't screaming. As far as the keyboard is concerned, when I'm using the keyboard on the mac as you can imagine certain keys take excessive abuse. I'm just curious how the machine holds up over time; something like a 3+ yr span. I have yet to run a macbook through long use, so I'm hoping the keyboard doesn't eventually weaken on certain keys. I'm also hoping that the system is designed to properly cool itself as to not experience premature hardware failure. Any feedback is appreciated! Thank you!
