So in case anyone see’s this I want to give a special shout out to @tkoham and @imhigh.today. As well as a shoutout to the discord group @tkoham pointed me too. As much as I wish it, I doubt I would have figured out some of these issues so quickly without there helps.
A brief bit of info about my setup: I’m using a mixed gpu environment:
Ubuntu host is Nvidia 1070
Windows Guest is AMD Vega56
I opted for the AMD Vega56 because I heard it was overall more reliable. I had attempted it before with a 1070 and a 1050ti. But, and this is my personal experience, performance of the windows vm was so spotty that I eventually switched to an AMD Vega56.
So far, I’m proud to report that performance is very stable. Some tweaks will need to be made to improve responsiveness of the system, some things to low slowly or hang. But the overall stability is what I really wanted 
However this isn’t where the story ends. As I mentioned, @tkoham pointed me to a discord server. They were incredibly helpful and quickly diagnosed the problem - a reboot issue with Vega56 gpu’s. Where the Windows 10 vm will not respond after the very first initial boot into Windows 10 vm.
I do not know why this is, this is just a fact. However I personally prefer this over Error43 in Nvidia. However your mileage may very. A number of users over on The Passthrough Post discord channel seem t use NVidia exclusively. So your mileage may very.
To anyone reading this and using an AMD RXxxx or AMD Vega56/64 gpu I encourage you to check out this post on level1techs. It describes a fix for the reboot issue in Windows 10. And so far it seems to work fine after several reboots.
For those of you who end up running a mixed environment like me I hope you find this helpful.
This is Jeff, signing off for the night.
