Your specs will be fine for the rift S. I personally have the index, and going from the rift CV1 (90hz) to 144hz, it's definitely smoother, but you get diminishing returns. Having 144hz is nice in eleven table tennis for seeing the ball, and in beat saber it feels more smooth, but the games are still perfectly playable at 90 (or 80hz on the rift S).

Boneworks can be a really punishing first VR game if you're susceptible to motion sickness. Stick to alyx, or other no-locomotion games like beat saber until you feel up to it. Pavlov is less bad than boneworks, but the smooth locomotion gets some people still.
