Okay. so have an update here. Updated to the latest Unraid today which addressed freezes when using a 2.5GB Realtek Card (which my computer had). Updating Unraid and running previous configuration made it SLIGHTLY more stable, but the remaining steps taken returned my PC to a normal condition.
 
A.) Reverting to old bios (one version back, v4602) using Flashback method. First I re-installed the current bios using Flashback. Then I waited, and installed the old version, just to make sure it was as clean of a process as possible.

B.) Once the BIOS was fresh, I realized that any tinkering I did in the past would be gone, and allowed me to focus on the only 2 settings that matter (from a fresh, default config).
IOMMU Enabled SVM C.) When creating VM, changed Virtio-net to Virtio, added my passed through GPU (with paired Audio Controller under Sound Card) and set my machine type to i440 7.2, installed, allowed Windows Update to grab WHQL drivers for display and network - then I received Black screen (known bug on my machine - i440fx does not like default WHQL from windows)
 
Note: I also did not VFIO bind GPU under "System Devices". Under "VM Settings" I have the following:
PCIe ACS Override: Both
VFIO allow unsafe interrupts: Yes
 
 
D) After driver installed and black screen - force stopped machine, changed from i440 to Q35. Windows login now displays when starting machine.

E.) CPU Pinning settings remained the same - isolating cores for VM specifically and allowing Unraid 2-4 cores.

F.) VM Ram was set to 32GB, I've read going beyond has iffy results.
 
G.) Ran a download test and wiggled my mouse around and everything is smooth again!
 
 
It could've been only one of the things from A-G, but something did it and I just wanted to document the process in case any one else encounters this issue. Thanks Unraid team for latest update, and forcing me to rethink the whole process resulting in a smooth download/network experience.
 
 
 

Adding a cache pool for domains, switching array to WD Red, adding pcie_aspm=off, switching SATA Cables, and adding new controller seems to have fixed it. 

Let the VM stay on over night, it hibernated, VM Paused, resumed the VM, and still stable. 
 
Solved for now!
