Ah! I have now. However, at the part where I run the commands to find my GPU's model, it doesn't seem to give the number I need:

I tried running the driver installer I downloaded, but right after running it, a message tells me a script failed, and asked whether or not I wanted to continue anyway. I selected "No" because I wasn't sure what happened. The file I have is named, "NVIDIA-Linux-x86_64-450.57.run", and the one in the tutorial is called, "NVIDIA-Linux-x86_64-390.87.run", so I was unsure if I had the right one!
UPDATE: I tried again to install a driver, opting to proceed after the "script failure" warning just to see what would happen. And, well, it completely borked up my Linux install! I logged in, and the panels were gone, and when I opened a folder, there was no title bar on the window, so I can't move or close it; even Alt+F4 doesn't work!
Also, I think I forgot to mention that I tried installing the drivers from the Ubuntu repository as well, but it couldn't find the packages.
