Ok guys, spent some time with the X3D.
Updated my conclusion, I had a faulty link cable that was actually hurting my VR frame rate with my Quest 2.
Using the VR preset on the Persian Gulf map, playing the AH64 live fire test range mission, I am getting a solid 72 FPS in the goggles and it never dropped below that even with tons of fire and smoke. The X3D CPU is giving a much more consistent and smooth experience in DCS VR. Very pleased. The 5600x was not as consistent, often dropping to 36 frames.
MSFS2020 in VR was VERY playable and enjoyable as well!
