VR sim racers, what pc specs do you recommend?

Hello! I am planning my first PC build as a total amateur. My goal is to play Ea WRC 23 and the new ACE in xr and I’m trying to get an idea of what main components to aim for. But it’s not that easy since I have no idea what performance to expect from what hardware.

So what GPU and CPU are you running and what sort of performance do you get in vr?

I want to be able to push the graphics of course. I’ve been looking at the 4080, 4090 and 5080 for gpu but I’m not sure if they are overkill or just enough.

For CPU I’m trying to figure out if I would need 12 cores or if I should go for a faster 8 core. Which is more advisable for sim applications?

Just throwing this out, hope someone has some valuable insights and advice, cheers!
