Just had a quick question before I went ahead and pull the trigger for my first ever MacBook. Has anyone done any testing comparing the processor in the base configuration compared the i5 3.1 GHz configuration? I don't know whether or not it is worth it. I obviously got the ram upgrade to the 16GB I would be mostly using the laptop for day to day use as well as light photography and video editing (I have a built pc for heavy duty editing). The thing I'm concerned about with the processor upgrade is that, while yes it would be faster and would reduce rendering times and such, how much more would it thermal throttle than the base config? The higher clock speed, with the same fans across the whole 13" spectrum I'm assuming, would no doubt produce more heat so while yes it might be better and faster for a short while but how much would it slow down compared to the base. Do you guys think it would thermal throttle to the point where the base model config would be better because it wouldnt throttle as much? All input is appreciated, thanks!
