In all honesty I think you may not achieve a VR experience that lives up to your expectations with your set-up - I would happy to be proven wrong!
I used to run a 6700k (i7 overclocked to 4.6ghz), 32 Gb 3000mhz ram, 2080Ti. While I could run in VR, the performance was rather lacking so I was really limited to sparsely populated areas to achieve a decent compromise between visual quality and performance.
If you have plans to upgrade/replace your PC at some point in nearish future anyway, it might be worth taking the risk - have you checked the minimum and recommended system specs for the G2?
