I haven't been following the Haswell rumors, but I think it's safe to assume that the 13" rMBP will not be getting a dGPU. Assuming an iGPU is all but certain, which one is the likely candidate? I'm currently running a late-2008 Aluminum Macbook, and my biggest complaint has always been the damn GPU (9400M). That, and the lack of an HDMI port, but I digress... Something as simple as web-based flash gives this machine a workout. The fans fire up like a jet engine, and a modest decrease in performance can be felt. When I tried playing COD4 on medium settings back in 2009, the frame rate was crap (somewhat jittery), the fan noise nearly drowned out the game play, and the computer was so hot it felt like it was going to combust. So, my question: How will the Haswell 13" rMBP hold up to light gaming? Does the iGPU doom the 13" to sub-par performance as the technology/software advances? Between the iGPU and retina screen, I'm worried that I might be making the same mistake twice. Aside from the ****** graphics performance, this is the best computer I've owned and I'd happily use it for another 5 years if only it could do flash/gaming reasonably well (which it doesn't). I really dislike the 15" form factor, so that's not even an option. Frankly, I'm surprised it's so popular - I don't consider it portable at all. Is it really so unreasonable to put a decent GPU in the 13"? The difference in form factor is so large that I don't think it would cannibalize sales of the 15"... and if it does, that just means Apple hit the nail on the head. Isn't that what they ultimately want? To produce the best product to meet customer demand? Any feedback would be appreciated.
