Do expensive CPU's and GPU's pay off in VR?

Today I’ve tried to fly PMDG 737 from north of Europe to south Europe.
I had so far 7 VR disconnections (Cable and Air) 2 [ Your graphics device has encountered a problem etc …](Warning: Your graphics device has encountered a problem - #41 by FlyingNautiker) 3 Unexplanable Freeze and CTD’s. I’ve rebooted my PC 2 times and restarting my Oculus 4 times and I’m still not done.
Not really what to look forward to.
