First post, please be gentle! (posted in the the Apple discussion/community forums for years, but tend to avoid now). I’ll shortly be pressing the button on a new 2017 BTO 27" iMac. Initial spec/thoughts were as follows: 27” 4.2 GHz i7 Radeon 580 32 GB Ram 1 TB SSD I’ve been lurking for a while just to gauge feedback on the new iMac models. Coming from a near silent late 2012 iMac I’m somewhat concerned about reported fan noise and heat from the i7 processor in the new models. I work in a small home office and love the silent operation of my current iMac. This got me thinking, should I just stick with the 3.8 GHz i5 rather than the i7 4.2 GHz upgrade? My work is 99% Adobe Creative Cloud (InDesign, Illustrator, Photoshop, Acrobat), although I’m planning on moving over to Lightroom from Photos. I don’t work with video (or Audio), just the occasional iMovie home project. My current late 2012 iMac is silent and cool at all times, I’ve never heard the fans ramp up in 5 years of use. Here’s the spec: Late 2012 27” 3.4 GHz i7 16GB Ram 750 SSD It’s still a great machine, but I really need to hand this down to my daughter as the 2009 iMac she uses is really starting to show it’s age! I understand Hyper-threading technology to a degree, but would there be any reason/advantage (based on my use) to go for the i7? Thanks in advance!
