That is the graphics controller that is included on your motherboard. It uses system RAM from your m/b, thus not requiring a dedicated video card like the GTX 960M. Depending on how much RAM you have on the m/b will affect how much using the Intel HD chip set will affect overall system performance. The more RAM you have the less of an impact the Intel HD will have on your PC. In most cases, use the dedicated board (in this case, the GTX 960) for better performance. Almost every video card has dedicated RAM so it doesn't take away from system RAM.
