The following needs I actually have for new MBP:
– faster GPU (like, much faster)
– faster CPU (any increase will be welcome)
Basically if I can run Sims 4 on it without the fan turning it into an aeroplane at lowest settings, I will be satisfied enough. It's fast enough for me really. I don't need it to be thinner, to have an OLED bar, etc. I'd like a black one but silver is good enough too. I can come up with some more stuff I would enjoy, but it's all unnecessary really. SSD is fine. Amount of RAM is fine. Photoshop, Reason, Illustrator, InDesign, OpenOffice plus the usual culprits like YouTube or M4A movies are fine, fast enough, I don't have to go get a coffee from nearest Starbucks waiting for Photoshop to resize a file. Battery life can always be improved of course, but it isn't exactly terrible right now. I love the screen and the trackpad is awesome. Just let me play a bloody game that's not even extremely graphically complex without worrying if my CPU will survive that. I've been advised on EA forums to put a cooling pad under the laptop when I have it on my desk. Thanks, Obama! Yeah, the point of having a portable computer is to keep it on your desk with a cooling pad...
What the few rumours suggested so far, though – USB-C only, OLED bar, rMB keyboard – makes me very happy that I snatched the 2015 version really cheap thanks to Brexit. I would almost like the 2016 to be terrible so that I am not tempted to update AGAIN.
PS. When posting diatribes about how a Macbook Pro is not a gaming computer please slow down right before page 1000 so I get to have a landmark post too!
RE: Running games on Mac and its Fan.
I play UT2004 and TF2 on my hackintosh and maxed out 2014 Rmbp 15". A 12 year old game played at 720p and medium settings will cause the fans to come on. Same scenario with TF2.
OSX just isn't properly adapted to run games. I'm not an expert but it could be due to lack of drivers, as even on my back which uses official videos GPU drivers, the fans will come on.
