What laptop is better would be for me for a mediocore gaming, recording gameplay and montage? rMBP 15" Late 2012-2013 with GT 650M or same spec same price rMBP 15" 2013 with Intel Iris Pro? Iris Pro model is actually a beast, it pulls games slower by 10-30% depends on the game itself, while being integrated graphic. Also I get 801.11ac, PCI-E SSD, longer battery life, lack of gpu switching (which is good), less heat, butter smooth OS X UI. HD4000+GT 650M model eats any game I throw at it, while having additional power to stream my gameplay online. But there is rumors that HD4000 can't draw OS X UI smoothly, and it lags and stutters. Can anyone confirm it? Does Mavericks fixes it? By choosing Iris Pro model, will I be able to record/stream 1080p 60 FPS gameplay on low-mid settings on games like WoW, D3, DotA 2? Windows-based laptops are no/no for me. I'm using Windows for 10+ years, it's just that I want to try something new in IT world to improve my skills and IT acknowledge.
