NVidia SLI
AMD Crossfire

This motherboard will support up to three graphics cards and is optimized for dual card operation.  If you are running a 48-Lane CPU then you'll get three slots with even bandwidth however, thanks to nVidia you’ll get to run two cards and like it.

For best video performance you will want to populate the top most PCI Express slot with your video card.  Try to avoid using the last slot as it will likely be running 8x or be disabled depending on your processor selection
