An update to my earlier post. I've set up new build over the weekend.
Win 10 Home 1809 build;
Ryzen 7 2700 stock speed for now (it loads up to 30-35% only with VR and adapter. Impressive in comparison to my 95-100% load on i5 6600K system);
Gigabyte X470 aorus gaming 7 wifi F8 BIOS.
Gigabyte 1080 Ti aorus Xtreme Edition 11GB.
Changed PCIe to Gen 3 in BIOS (which doesn't matter on this MB, but still).
Placed WiGig card in the first x1 slot (closest to CPU) which is Gen 2 I believe by specs.
Installed all the software, fired up, played for a few hours. No BSOD or freezes. Just having some latency issues once in a while but that might not be related to wireless adapter itself but my network. Very nice.
