Use Intel by Default and nVidia for a little bit of PSX Emulation

Okay, so I decided to post this just before I do anything that may break my system.

I have Manjaro KDE minimal Installed with bumblebee as Graphics Driver.
My Laptop is Dell Inspiron 1555 Series with Nvidia 920M

My goal is to have Intel used by default (Current) and Nvidia to take over PCSXR, PCSX2, and PPSSPP.

Now I am not very confident, how I would do this. Because I already have a Driver Installed which is Bumblebee, If I also Install Non-Free Driver for Nvidia will there be a conflict?

I am currently reading this and trying to understand first. but of course, I still want some input from you

Please see my System Info below:

Why am I asking first?
months back I tried to sudo nvidia-xconfig
then a config file is generated in /etc/X11/xorg.conf

afterwards, I restarted the system, then BAM! No UI. It took me days before I could restore my system.
