The thing is rhe benchmark means nothing.

If the pc plays the game acceptably the bottleneck means nothing beyond they likely overspent on the card.

Chasing numbers is pretty silly. After a cetain point the framerate goes up but it makes virtually no difference in the player experience.

Chasing 120 fps is for people who have nothing better to do with their money. Most of the research suggest a cap of 60 fps for the human eye to register. Some research points to maybe as high as 90 but even then most cards on the market these days can acheive that easily.

it's kind of like buying a gallon of milk when you only drink a glass a week. sure you have more milk but you dont really need it. You would be much better off buying a quart.

Yup bottlenecking is a thing to be sure but again after a certain point that only means you spent too much on the card or you have room to grow in the future assuming the experience you are getting is acceptable.
