Stuttering RTX2080 and recommended controllers

Im only running in 1080p as thats all my monitor is. Im struggling to get 30fps on medium.

Ive gone through the settings walk through on here and nothing changed.

Its running on a 1tb samsung evo ssd.

Ive gone and ordered new ram and a new cpu.

If this doesnt work im at a loss.

The psu is a corsair gs800w.
Admittedly its about 7 years old, but never had an issue. Only when i changed to a more powerful gpu
