Okay, thanks for the help!G'day @Freez and welcome to linux.org
Our site name may confuse, we are not directly associated with Linux, and we don't have a database from which we can pluck the information you ask.
So simple answer is we would not have a clue.
Your best bet is to arm yourself with a USB stick or two, download a Linux .iso of the one/s you want to try and burn them one at a time to the stick/s.
Then you boot the computer and enter your Setup and change the boot order to boot the USB first, and enter the Live environment. From there you can see how your Monitor, graphics, wifi, &c, go.
Ask any questions, and take a look at our new Gaming section here, for ideas - https://www.linux.org/forums/linux-gaming.202/
Another question, do you know what scaling mode is? If yes, can you change scaling modes in linux specifically for games like CS:GO to have a stretched image or an image with black bars?
