The VR headset probably is not going to be as effective to aid your development as it is primarily in the main line of site in the same manner as a good size single screen. The edge of vision will be darkness. It will however be quite a lot tidier!

I am happy to help - it will depend on a few decisions in my experience.

If you want to do something on a desk or go to the full honky?
You can blow £15,000 on a serious gaming system, chair, monitors etc.
You can get away with £2400 on a three monitor desk mounted system.

What are you going to use it for?
The modern car games are quite amazing but can feel unrealistic unless you have grown up on computers for many people including me. I am rubbish are car racing games as I can never get a feel for the car through my bum and so constantly crash. I would look at flight simulator, the new version is amazing and the game has been engineered for visual display. It would allow you to increase the other planes in flight and also fly around things on the edge of your vision. https://www.xbox.com/en-GB/games/microsoft-flight-simulator. Different pedals same tin.

Practice
New XBox Series X
65" UHD TV, sit quite close
Simple Logitech wheel or joystick (flightsim)
MS Flight Sim 2020 standard

Chunky Upgrade to

Don't go nuts but make it good specification.
3*27" monitors 1080p FHD which need to offer >120Hz refresh rate so there is no flicker to make it most effective for your eyes. £700
These can be desk mounted on a decent stand or one of the seats/frames. I would recommend Next Level Racing kit if you want to go the full way with floor mounts etc.
A decent PC in the region of £1500-£1800 in total, a lot of that will be the video board, don't skimp.
You can sit reasonably close and get an amazing view width using the three monitors.

Okay I am enjoying this now - addicted

Go large specification (plus room to fit it in and approval if you are wise!)
