With the latest updates now pretty much all Macs can drive a 4k monitor at 60hz (notable exception the Mac Mini). Question is: are these 5th gen Intel CPUs able to drive a 5k monitor like the Dell UP2715k at any refresh rate? I understand that so far that monitor needed two mini/dp buses to work. Not sure if a more powerful CPU/GPU can make up for that (Skylake?) or whether the bottleneck is the connectivity. I think 5k 27" is where eventually I would like to end up.
