Currently I am using the first gen rMBP, which is max out. I am pretty happy with it because of the 16gb ram that it has and it could handle multiple task such as Lightroom exporting and FCPX exporting. However, the part that I am not so happy is the GPU(650m). It is okay when I do task that can wait I.e export and rendering. The part which is not okay is when it comes to gaming. I play only battlefield 4 on it, and the current rMBP can play at 1920 x1200 at some max and medium setting with little AA. By the way this overclocked with MSI which it is around 40-50 FPS. So my question is: is it worth it to get the new rMBP with 750m and upgraded CPU. OR should I wait for maxwell GPU which uses unified memory in the 2014 rMBP?
