I've done some research and what ive found is that on paper the 540 and 500 are near identical and for minor gaming, streaming, etc. I shouldnt notice a difference, but I've seen people saying that with the touch pro 4 or whatever the 540 doesnt perform well, does it really make a difference in the newest 2016 macbook pro's? I would like the ability to play a few higher end games if i choose, though I prefer a console. I guess my main concern was the people saying the 540 was throttled extremely low, is that true of the new 2016 macbook pro 13? looking to go with the i7 and a 500 gb hard drive, 8 gb ram is more than I see myself ever needing.
