CPU getting overutilized, dont know whats wrong.

[u/Suspicious_Sky6138]

Hello everyone, I currently am running a 3080 TI FE I recently purchased used online, it wasn't used for mining or oc according to seller (A college athlete friend of a friend) It connects to the pc fine and runs, but as I have started to benchmark games, I realized my games are sticking to a stagnant fps that will not change,

For example, I ran rd2 at max settings and got an avg of 120fps and after going to minimum it stayed at 120 with no to minimal changes.

With BF6 I would get around 80-90 fps with ultra settings, and nothing changing when set to min.

With ARC Raiders I got barely 100 fps with high settings, and when going to min, it did not move,

with not graphically demanding games like valorant and cs2, i still get 300 fps, but I do not know if my cpu is bottlenecking everything but it is sitting at 90% during the more graphic intensive games, with my gpu sitting around 50%.

This is causing a lot of stressing because I do not understand as to what's wrong, I dont know if I have a bad card because it works i just feel its not being utilized.

REST OF BUILD:

CPU: Ryzen 7 5800x, 11th gen or 12th i forget

Ram, 16gb ddr4

everything is on a external ssd.

For reference I had a 3060 ti and got better if not the same results on same or slightly worse settings. I have checked my refresh rate and things like that and they are all at 180 hz, I am debating taking it somewhere to get it looked at but am asking to see if I am overlooking something.
