Bit off topic but to obtain a very capable 4k PCVR system with all the new components coming out:
Man that's over £1800
- 5900X + new X570 mobo (£740)
- PCI gen4 M2 SSD (£170)
- 32Gb 3600 ram upgrade (£220)
- Nvidia 3080 or AMD 6000 series GPU (£700)
That's only if you want to get absolute top performance. You could build a machine cheaper than that and get accepable VR peformance.
But then you can buy a Quest 2 for £300 and play a large library of VR games with acceptable quality.
