800 fps is a lot, but there's only so much can be judged from a static screen that was capped in a small room inside the game, run the benchmark and give more data, like what are the 1% 0.1% low fps you're getting on average, if those are stable then yes.

I also suggest you to limit your fps since it can strain your cpu to some degree. it's not like you see those frames on a 144hz or a 60hz monitor anyway
