So I'm slowly coming around to thinking about buying a new iMac. I want a 27" Retina one, but when I buy new computers I like to buy when a significant technological leap has been taken. Unfortunately, I have not kept up with all the new developments in computer hardware, so I need a bit of help. My use scenario - I do the usual low-demand stuff like surfing the net and word processing, but also a bit more intense stuff like video editing, so a good chipset is a must. My question: 1) Intel has been really slow coming up with chipsets that are any kind of performance leap in the past few years... it seems like the changes have been incremental rather than substantial. Question: are the latest chipsets a decent leap in capability, or not... and if not, is there sense in waiting a few more months to see if Intel comes up with something that Apple can stick into their iMacs and that will represent a decent upgrade - basically I have not been following Intel's roadmap. 2) It's all well and fine with the display being Retina, but resolution is only one factor in a good image for photo and video editing. A very important factor is color gamut, rendition and accuracy - here is an article from 2014 that's critical of the Retina displays from that point of view: http://thisweekinphoto.com/27-imac-retina-5k-color-gamut-question/ For photo and video editing and color correction, obviously this is a very important question. Question: has there been any progress on the color in the recent Retinas or is it the same dreck as in 2014 3) Quality of SSD. It's all well and fine to have a fast drive, but there is varying quality of SSDs out there, and Apple has not exactly impressed with their choice of SSDs. Question: has the quality of SSDs that Apple sticks into the iMacs improved any? Any other leaps in capability are also of interest. Thank you in advance!
