I upgraded the RAM to 32 GB from OWC and saved about $300 compared to AppleвЂ™s RAM prices. I figured that, since I was spending the money for a high-performance screen, IвЂ™d max out the rest of the system. When I bought this system, I configured it for video editing. (Intel is rumored to be having problems delivering the next set of chips, which, if true, means that it will be a while till we see significant performance upgrades in these computers.) HereвЂ™s a good article from Extreme Tech that examines what Apple is doing under the hood to make this screen possible.ДЄside from the screen, though, the rest of the computer is essentially the same as existing iMacвЂ™s because they are all using the same family of Intel processors. The big difference in this computer is the monitor. Additionally, Apple has introduced something it calls Compensation Film, which helps ensure solid contrast even when viewing the display off-axis.вЂќ ( MacWorld review) This is accomplished through the use of more efficient LEDs along with a special timing controller that coordinates the pixels. And it does so, according to Apple, while using 30 percent less power. вЂњSpecifically, this iMac projects 14.7 million pixels (at a native resolution of 5120 x 2880 resolution), which is four times the pixels offered by the standard 27-inch iMac. This means the 5K iMac has four times the pixels of a standard 27вЂі iMac! What Apple has done is double the scale of the 5K iMac from 2560 x 1440 pixels (Retina iMac) to 5120 x 2880 pixels. There is no question that iMac systems are stunning to look at. NOTE: IвЂ™ve had problems with screen captures with the 5K iMac. The 5K iMac fits comfortably into the iMac family, though at the high-end of the price range.ДЇrom my perspective, if you need the increased screen resolution for editing 4K вЂ“ or larger вЂ“ video files, or need all the pixels you can get for high-resolution Photoshop work, the 5K iMac is the perfect system.ДЇor anyone else, I recommend a Retina-display 27вЂі iMac because, if you exclude the higher resolution, the specs between the two are about the same. Yes, the MacPro is faster, but, given current configurations, the significant increase in price is not offset by enough of an increase in speed вЂ“ especially regarding video compression and, to a lesser degree, editing. They are an excellent balance of power vs. I am a big fan of 27вЂі iMacs for most video editing. This isnвЂ™t really a вЂњreview,вЂќ since IвЂ™ve already purchased the unit. IвЂ™ve been using it now for around two weeks and wanted to share its strengths, weaknesses and my reactions to using it. And, after a wait of about 3 weeks, my unit arrived right after Thanksgiving. Since I was in the process of buying computers for our new office, I decided to add one of these to my shopping list. October 16, 2014, Apple upgraded their venerable iMac to a new 5K display specifically designed for image and video editing.
