Cap FPS at Monitor?

Just got a new pc. Old one only went up to like 120fps on my 144hz monitor but the new one goes to like 400+. Should I cap it?

more fps = less input lag

what specs

If your worried about temps then cap your fps
If your not worried about temps at all and you want less input lag then cap your fps at 400

only time i really worry about caping fps is when you get drops in frames. For example, on apex i cap my frames at like 170 because i go from 300+ frames 180-185, because of the insane amount of stuff that happens late game. Caping it makes the experience feel like volatile
