I am looking at buying a 15' rMBP soon, mainly because of the display and my old 13' 2010 machine. I am thinking of getting a 2013 low end 15'. I would be using the computer for basic college tasks and some steam gaming maybe skyrim, GTAIV, portal1/2, dark souls ii, farcry 3, and maybe some CAD design next year. I am thinking of keeping this machine 3-4 years and my main concern about this computer is the unupgradable 8gb RAM and the Iris graphics. Do you guys think this RAM and iGPU will sufice for gaming and future applications for the next couple years? I am strongly thinking of getting the 16gb RAM/ 512gb with the dGPU just for those reasons, either a refurb 2012 or 2013? who knows I know there's an update coming soon that might feature broadwell, which I've read will help with graphics performance. Would my machine be completely outdated with these new chips if I decide to get a 2013 or 2012 15'? I need to know if I can take my chances and buy these machines now and hopefully not be outdated by these new chips. I read that the change from the 2012 15' rMPBs to the 2013 models wasn't that big, so I'm wondering if that will happen again this year or early next year with the new update. I am aware that these are all predictions btw. My current machine is 2010 MBP 2.66GHz intel core 2 duo with 256SSD and 4GB of RAM. I've been upgrading through out the years, something I won't be able to with these machines.
