Over 90. The Index goes up to 144, but I don't think you're going to be able to get anywhere near that in most games. You might have trouble hitting 90 in some games too though.
>I'm not looking to really go above 60 in VR
You really want to stay as close to 90 as you can to make sure things feel smooth.
>The biggest draw about the index for me is that it feels future proof, like it'll still be relevant in 5 years or so.
Index will definitely be replaced in 5 years, and it'll get some price drops well before then. I wouldn't get one now unless you want it now.
