Hi and welcome Archdevil,
Display-Settings, the new graphic card manager is not ready yet. Meanwhile, you can install and activate the Nvidia drivers using these instructions :
1) Install the following package with package manager :
xorg-video-nvidia185
2) Open a terminal :
ALT+F2 -> konsole
3) Copy/paste the following commands in it and then press the ENTER key :
sudo zorg --driver=nvidia/xorg-video-nvidia185
4) Restart your computer
Hopefully you will see the Nvidia startup screen at reboot.
