Any of you running a 5K external display with your new iMac? If so, which iMac with which CPU and GPU, and do you notice any lag in the animations?
I noticed an occasional lag on even just the native screen (with no external screen) of the MacBook Pro 15" 2.8 GHz with I believe the Radeon Pro 555, but it was mostly lag free. I couldn't imagine it'd be lag free with dual 5K screens attached though, like they list as a supported configuration in the specs.
I'm curious to hear about your experiences running the 5K iMacs with an external 5K screen.
