"The X99 platform is an expensive platform to go into. The processors are expensive, the quad channel DDR4 is expensive, and the motherboards are expensive as well. With Gigabyte’s second round of X99 motherboards they wanted to bring out a fully-featured board that could get you on the X99 platform at a reasonable cost. This is where the X99-SLI comes in. It is very much like Gigabyte’s X99-UD4, with a few features left out. Probably ones most users won’t even notice. You still have an all digital power design, 3 and 4-way graphics support, dual M.2 slots, SATA Express, Gigabyte’s AMP-UP audio, and much more! If you are looking to get into the X99 platform and want a solid board that is not going to break the bank this could be the board for you. Let’s see what it can do!"
