1070 is definitely good enough for Index. That's what I had when I got Index over a year ago. Maybe you don't run 144hz everywhere but it's a more than decent experience. I ended up upgrading to 1080Ti since I got a really good deal on one. You're good starting with a 1070 and then upgrading when it feels limiting and 3070 and amd's new offerings are out.

You have to keep in mind that vast majority of VR games are optimized towards Quest/Rift S quality or even Vive as baseline so small text is basically a special case for simulator games. G2 is probably not worth it unless you're into flight sims.
