Hi, I have a 27" Mid-2010 iMac., 2.8Ghz, Intel Core i5 CPU with 12 RAM and a 1TB HDD. It is a machine I use every day for web browsing, email, watching the odd video, photo editing using Adobe Photoshop Elements 14, occasional use of flight simulators and an occasional bit of video editing. I am considering upgrading to a 5K iMac, but would appreciate some thoughts - would I gain much given my use case? The iMac gets used every day and I like the idea of a better screen which I could scale to get more screen real estate which would be welcome. Any thoughts on whether it would be worth buying a new Mac?
