ASUS provides a set of utilities and added value software options to sweeten the pot. AI Suite 3 just works. It gives you just about all the configuration options you will need to use while working in the OS. As sub components, you get improved throughput to external USB 3.0 devices with USB 3.0 Boost, faster USB charging of both Apple and Android based devices, power management flexibility with ASUS EPU, and an unparalleled level of fan management with ASUS Fan Xpert 3. ASUS Crystal Sound 2 is based on the Realtek ALC 1150 codec seen on many of the upper tier Z97 boards and delivers excellent audio for an on-board solution that allows the end user to enjoy the sound quality without bending the budget further. Not billed as a gaming ready board, the X99 Deluxe is fully ready and able to deliver up to quad-GPU SLI and CrossFireX compatibility using dual-GPU cards and up to three-way SLI and CrossFireX solutions using three cards.
