Recently upgraded my system so I'm re-posting

CPU: AMD Ryzen 7 3700x (unchanged)
RAM: 64GB DDR4 3200MHz (unchanged)
GPU #1: NVIDIA GeForce RTX 2060 6gb (dedicated to Linux)
GPU #2: NVIDIA GeForce RTX 3060ti (dedicated to Windows)
Also upgraded to a 1000w PSU from a 650w to accomodate the new GPU.

I did this upgrade to give me more flexibility, I can have a Windows VM with the 3060ti for gaming and heavy-duty gamedev work, and I can use Linux for everything else. I no longer have to deal with Single-GPU passthrough either, so I can use both OSes at once using looking-glass for Windows.
