Hi,
I actually solved it with a mixture of solutions

– I rendered out in 8 bit, wich was totally fine
– i rendered the individual 4x 4k , 60fps clips separately as it had to be stitched together by 4 synced players anyway.
– i upgraded my Gtx 970 4GB to a Gtx 1080 ti with 11gb wich made working much more comfortable
– in the secret Pref Settings in AE I set empty cache to every 10 frames, wich I later set higher again, but it`s a good starting point.
I still had a couple of render fails wich have been disappeared after the latest AE update.
I also found a couple of effects caused problems in 8k rendering (Glow for example) I tried to find out where in the render the fails happened and pre rendered the Comps or layers causing render fails. Took all quite a bit of troubleshooting time but worked all out in time.

What worked for me was this:
There are 2 apps, gpu-z (win) or cuda-z (mac)
I was just launching cuda z on mac (it monitors the gpu details) and than started after effects …. BAMM! couple times as fast on realtime performance on GPU accelerated fx like glow.
I don’t know what it did but it worked… all the Terminal Cuda suported card .txt. stuff i’ve been doing since cs6 didn’t really do anything for me in cc2017. will try gpu-z on windows too.

Thanks guys.. I am aware that this changes the subject.. but anyway, I solved it by just installing OSx 10.12.3 on a new SSD on my machine and now everything is just great. It took just as long as installing windows. As a long time mac user I got so tired of all these little Windows issues. What can say. So far its absolutely snappy. Everything works, the benchmarks show that osx is even a bit faster. I can just say the GUI feels snappier.
here are the results, same machine, Mac vs Win.. Windows was on a faster drive Samsung NVMe 950 pro OSx on a Samsung 850 Pro ssd.

here are the benchmark results here if anybody is interested,

….i found a workaround with applescript myself… sometimes it`s great not giving up too soon:-))
maybe there is a more elegant way.. but this works.
compiled as app and used as login item.
AE render seems to remember the last watch folder selected, so i didn`t have to set the path.
might look quirky to a pro, i`m just happy it works,i`m not a programmer and just collected and tried snippets of code until it worked.
