The last GTX video card I installed came with software to allow me see how the video card is performing, speed, temperature, etc. and to make adjustments, but this Radeon 5700 XT does not have any such application. If there is such an application and I have not found it yet, apologies.
It's called wattman. Right click on your desktop. Click AMD Radeon Settings --> Gaming (upper left) --> Global Settings --> Global WattMan
