Considering doing the same thing. I really do not like the compromises of the latest models. But -- were you able to get the model with the discrete GPU? I find the Iris Pro slow when driving an external 4k display, so I wanted to get a model with the discrete GPU, but it seems only integrated graphics models are available.
- pier25 10y agoAuthor here. I got the one with Iris Pro. I was a bit worried about performance but after using it for a couple of days I'd say it's more than fine. I haven't connected it to a 4K display though. I will try that and get back to you.
- jwr 10y agoYeah, well, I know that Iris Pro is slow with an external 4K display. Not just 3d, even moving windows around is sluggish. I was hoping it is still possible to buy a 2015 MBP with a discrete Nvidia GPU in it.
- pier25 10y agoI'm using a Dell P2415Q using the provided mDP to DP cable and it works just fine in 4K at 60Hz. Maybe you were using it at 30Hz?
- jwr 10y agoNo, at 60Hz, but we might differ in the definition of "fine" :-) Moving windows around isn't smooth, resizing large windows is noticeably laggy, things like expose seem slow as well.
