I need a new laptop for school. I want this to last at least 3 years, if not longer. However, I don't know how long I can wait. I was looking at the rMBP 15" since it has a dGPU, though only 1GB. I want 16GB of RAM and 256GB for dual OS. 13" rMBP has only iGPU. But Haswell is said to come out in October. Is it worth the wait? Battery life won't mean much to me since I won't be gone for 12 hours at a time. I like the retina display plus in Windows, 2880x1800 is nice, I like to have the desktop space. But apparently the dGPU has frame rate issues because of the high resolution? It has problems keeping up a decent FPS. Is this true? Or was this solved with Mountain Lion (Anandtech's review is pre-Mountain Lion I think?). The uses: Coding JMOL Video editing Word Processing Movies Few games (not demanding. Mostly either Dota 2 or some old games or indie games. Nothing top of the line. That's what my PC desktop is for) Edit: Is it worth going from the 2.4GHz to 2.8GHz CPU? Also, apparently wireless AC is coming to the new rMBP, but there isn't a single router that has AC at college or home, so it's not a necessity.
