Gigabyte is going crazy with the wireless options available to you in their X79 series of motherboards.
With Bluetooth 4.0 available your iPhone 4S will be able to connect seamlessly to your Gigabyte motherboard. The biggest improvement in the new standard is the power savings which it enables, something that iPhone 4S users are desperate for. In fact if the attempt to standardize 3D glasses over Bluetooth 4.0 succeeds then one of these motherboards will be perfect for building a system connected to a 120Hz 3D monitor.
As well, Gigabyte has extended their WiFi support to a dedicated card which sports dual antennas, one for WiFi and one for Bluetooth. They also support the new Bluetooth Smart which is designed to work with a large variety of single use devices. Your blood sugar monitor, house thermostat, security systems and smart watch could all connect to these motherboards as easily as your phone, headset or other Bluetooth devices.
