Looking for more of a real world experience from a photographer's perspective. I am a commercial photographer and my main computer that I do all my real processing is a loaded retina 5K iMac which is great, love it. In my studio, I have an older 24" iMac and a 13"MBA which both drive me nuts because of their slow speed both processing and USB as well their screens suck. I have been holding out for the new 15mbp to replace them both in the studio. The main usage is just shooting while tethered and previewing images so that I can make adjustments to my shot. Colour isn't super important as everything is calibrated but brightness and showing true whites is and with my current setup, have to pay very close attention to histogram cause the screens are so dim. I normally won't be doing a ton of photoshop or lightroom on it on a daily basis but definitely will at times, especially on location shoots etc. So with that said, looking at benchmarks, I am not really seeing big improvements over the 2015 models. hell, even the 2015 2.2ghz model isn't all that bad in comparison and I save $1000 and can get one today. The money isn't really all that important but I do put weight on value. I don't mind spending if I get $1000 more value out of a 2.6 with the 460 upgrade but not sure that I will. So just looking for opinions on saving some money and instant gratification or waiting until january for a custom build and dropping an extra grand.
