I am interested in buying the 15" rMBP. I have one issue that worries me. I have read that a lot of the rMBPs throttle comparatively easily. Since I intend to use mine to let it compute stuff over the night (being at 90+% cpu for 12 hours straight or more), I really don't want it to throttle thus making the calculations take longer. I have an old (2006) Macbook Pro and I had it work at max cpu 3 days straight and it never throttled (although it was uncomfortably hot). So my question, how prone are the rMBP to throttling? Is the situation I described above sure to make it throttle? Maybe I will better off with a cMBP? (since it's slightly bigger so maybe it cools more reliably, and it doesn't need to throttle as much). Thanks in advance.
