Yeah, I use an Index with Assetto Corsa, ACC, and some other games. Assetto Corsa requires a lot of customization to get up to speed, but is worth the effort. You will need a better graphics card unless you're fine with lower graphics settings. I have a 2080Ti and it's great in AC. ACC lags a bit but it looks great and I could dial it down to make it smoother. VR is definitely better than any flat screen setup in terms of depth perception, immersion, etc. It's hard to describe. Here's a video I made of a motorcycle addon for Assetto Corsa. This gives you an idea of what it's like in VR maybe a little. Massive immersion.
