Ok I tell you what I would do if I wanted to change PC today and if I wanted vr.
For the GPU obviously I would choose 2080ti or 2080super, they cost too much imho.
For the cpu, amd, this is because intel is falling in performance and will continue to fall, paying for intel is wasted money. So better wait to see what both intel and nvidia will come out in the future.
1000 dollars today still 1000 dollars tomorrow
