The first variable is VIDEO_CARDS. This is used to set the video drivers that you intend to use and is usually based on the kind of video card you have. The most common settings are  for nVidia cards or   for ATI cards. Both have actively developed, well-supported open-source drivers. If you have a newer AMD video card (Southern Islands and up), you may also try the new open-source  driver. See the AMDGPU article for more details.
