z170x-ud5 th vs iMac

[LocusOfControl]

I finally decided to give up on the i7 z170x-ud5 build and buy the 5K iMac 

 

Spent 2 months of weekends trying to get rid of reoccurring black screens with the R9 390 and the thought of a 5K screen was too much temptation so decided to go for it. I now have the 27" 5k i5 with 500GB flash, 16GB Ram, R9 395 and very nice it is 

 

The z170x was pretty good apart from the black screen, managed to stop the GPU hang but still occurred even after 8 hours when scrolling quickly with a magic mouse! (no error other than the memory address and debugger line - I have a cyberpower ups so know that its not a power issue although there may well be multiple causes of black screens IMHO). I was using a 5k i7 profile and had gradually reduced most of the errors in the system log, only issue bothering me being black screen and lack of sleep.

 

One thing I noticed is on the hack the read write speed of my samsung ssd was approx 600mbit/s while on the iMac its like my mac book pro at about 1600+ read and 1100+ write. And sleep obviously works and the display is gorgeous!

 

So thanks for all the useful info since Leopard and good luck !
