Using that laptop in Linux was the bane of my life, Optimus is hell and if you want to switch between Intel/AMD you need to reboot, no thanks.
You can't use it for VR if you have the type of Optimus I had, where if the display was connected to the Intel rather than to the Nvidia, it wouldn't work. If you left Nvidia on, and tried to use it as a laptop, you'd be lucky to get 20 minutes battery life (not exaggerating), so it was neither great for gaming nor useful for productivity.
