It features an audio / LAN combo card, called ROG ThunderBolt. The audio portion on the ROG  ThunderBolt was created for use with a gaming headset and uses XONAR’s superb audio material to  provide four times the audio quality of that of a regular sound card, and an extra built-in headphone  amplifier powers up every minute sound detail with optimized impedance settings.   Networking is powered by Bigfoot Networks Network Processing Unit (NPU), detecting and  accelerating gaming network data in real time. The combined audio and LAN features on the ROG  ThunderBolt and the revamped Rampage III Black Edition will bring foes to their knees once again.  Rule your game with Rampage III Black Edition.
