What kind of graphic design software is most commonly used with a PC?

I am an aspiring graphic designer and I have a Dell,which is obviously a PC.I was wonder if there were any graphic design softwares out there that could be used with a PC.

Any help here?

If you want a free one, GIMP can take a little bit to get used to but it’s good once you get the hang of it.
If you have some cash, Corel Photoshop pro costs $120 last I checked for the latest version. I only use it because my cousin bought if for my birthday and it’s amazing.
Paintshop is a bit weaker in my opinion but a good $30-$70 depending on the version.
I also bought Printshop Deluxe for $50 before I got Corel.
