Upgraded gpu and psu and now have terribly slow performance.
I recently decided to upgrade my gpu so I purchased a 6800xt from amazon and installed it. I used DDU to uninstall old drivers and then installed the up-to-date drivers. Now my PC is incredibly slow and would take 10 minutes to launch any game and I would get basically 1fps in any program. I was told my psu wasn't powerful enough, so I purchased a 850w corsair and installed it. This had no effect, and my pc basically runs the same. The PC barely utilizes the cpu or gpu when I try to run games and I am unsure what to do now as I may have to take it to a pc tech. If any one has any ideas or solutions it would be greatly appreciated.
Specs: Msi aegis zs 5ds-263us. Installed a merc 319 6800xt and a corsair rm850x 80 plus gold fully modular Atx.
