mgbgt35 Indeed, the Q3 display alone is not a huge upgrade over Q2. But together with the improved lenses the upgrade was good enough for me to not skip it.
I'm not using PCVR, so cannot give any robust advice and leave that to others. As a note, a PC optimized for editing VR videos may not necessarily also be optimized for PCVR, depending on the GPU you have. If your GPU was more expensive than a Q3, it may work...
Acc. to others in this forum, Galaxy XR has the best display image quality right now (even better than AVP), but I have not noticed anyone using it for PCVR.
