Before buying a new GPU, make sure you check your hardware first. If you are not sure about it, you can download CPU-Z software on your PC. This app will provide you all the information regarding what components you use on your computer.
There are other factors to consider like how much memory you have, your power supply, the size of your case, and what type of monitor you're using. Moreover, you should have twice as much system memory as your graphics card has VRAM. In case, if you're running a PC for more than five years, sorry to say that you should probably consider a full system upgrade.
Set your budget
If you are going to buy a new one, figure out which graphic card will suit your system. However, keep it in your mind that don't spend more for a graphic card than the worth of the rest of your PC. It is always better to keep the cost of GPU one-third of your PC.
Also, you need to jot down the idea of the graphics settings you want to run on your system which includes resolution and quality. Make sure yo buy a card that you won't be changing it for at least couple of years.
