I recently got an RX 570 8gb for Christmas. I replaced my GTX 750 ti with it. Installed newest drivers and my computer is much slower and the Radeon graphics app doesnt recognize I have an AMD card. In device manager, under display adapters it show I have an RX 570 but theres a little yellow triangle warning symbol beside it. Going into properties it says that there was a problem and windows stopped the device (error code 43) I can't launch csgo but I can Rainbow Six: Siege and it ran at about 2-3 fps when my 750 ti got 65+. Fans also run and shut off at random. Uninstalled all Nvidia and AMD drivers, reinstalled AMD drivers, uninstalled AMD, drivers, reinstalled older ones. Nothing. Nothing has changed at all. My PC specs are an i5 4460, 12 gb ram, RX 570 8gb, Entec 520W 80 bronze certified, and have never had any trouble out of any of my components.
