2x 10 Core CPU, 32GB RAM, 8 DISK RAID, GTX 980 = no butter smooth scrubbing??

I'm coming from PP on osx with a 12 core mac pro and a raid with 4 disks pushing 300 MB/s.

Prores performance was butter smooth, 4K raw playback and editing was possible without issues.

Now I switched platforms to a much more modern system but scrubbing and overal timline performance is far from satisfying... I just don't get what's wrong.

The playhead from the timeline is sluggish when scrubbing, I don't see all the frames, it constantly skips frames giving a choppy preview when scrubbing (with DNX footage). There is also a lot of lag between the mouse pointer itself and the playhead line.

Playback has no issues so far.

It improves slightly when minimizing the timeline tracks to the min height.

But is this a bug? Because I put together a beast of a system that should shred this kind of light workload.

My disk IO:
