I am looking at upgrading my current laptop and want to make sure that whatever I buy has sufficient specs to edit GoOro videos. I prefer the portability of the Macbook Air but I suspect that the rMBP might seem like a wiser decision (both at 13"). The new 12" Macbook looks awesome but impractical so I reluctantly am setting it aside. I currently own a 13-inch, Mid 2012 Macbook Air with a 2.0GHz Intel Core i7 (Turbo Boost up to 3.2GHz) with 4MB shared L3 cache, 8gb of memory and 256GB flash storage. I found I was getting some skipping when playing GoPro videos. GoPro's website states that: "For higher resolution videos (1080p 60fps and higher): We recommend at least 3.0 3.7 GHz Ivy Bridge processors (third-generation Core-based processors or AMD equivalent), 4 GB RAM, and a graphics card comparable to an NVIDIA GeForce GT 650M. The graphics card and processor speed is important particulary for 4K and 2.7K resolution video playback." I want to upgrade my laptop to try to correct this skipping issue and also because I am maxing out on internal memory (from 256gb to 512gb). The three machines I am looking at are: 13" rMBP - 2.9GHz Dual-core Intel Core i5, Turbo Boost up to 3.3GHz (Intel Iris Graphics 6100) 13" rMBP upgrade - 3.1GHz Dual-core Intel Core i7, Turbo Boost up to 3.4GHz (Intel Iris Graphics 6100) 13" MB Air - 2.2GHz Dual-Core Intel Core i7, Turbo Boost up to 3.2GHz (Intel HD Graphics 6000) Do any of these machines fit the bill for what GoPro recommends? I really get confused when it comes to the speed as to the significance of the type of chipsets used and the Ghz that they tout. Any help deciphering this madness would be awesome. Thanks in advance.
