Well I finally did it. I pulled the trigger and ordered a 27" with the following specs: 4.0GHz QC i7, TB up to 4.2GHz 8GB 1867MHz DDR3L (2x4GB) (Already ordered 32GB upgrade on Amazon) 1TB Flash Storage AMD Radeon R9 M395X w/4GB I only hope and pray that this machine does not suffer from the awful image persistence issues that all 3 of the last iMacs I tried had. https://support.apple.com/en-us/HT202580 I can't imagine for the life of me why this has been an issue that has plagued iMacs going on now for over 3 years. Surely Apple can fix this...? It does NOT happen on all devices as some people will argue, so why can't they get it straightened out? Obviously Apple acknowledges it, hence the support doc that I have linked above. I have noticed a few posts on here about it too, one being mine. Anyway, here's to hoping this machine does not have it (or any stuck pixels for that matter). I am also posting a poll with this thread. Before you respond, please take the time to actually test your iMac screen using the following link: https://marco.org/rmbp-irtest.html Leave the checkerboard screen on your display for at least 10 minutes so that the results are accurate.
