What you'll be amazed to see here is the support for DDR3-2500 MHz!  The nearest modules that are available to the consumer at that speed are often high end, low density kits from Corsair and Kingston, at loose timings and several hundred dollars per gigabyte.  Perhaps there will be resurgence in high end, high speed memory kits as a result, after Sandy Bridge knocked memory overclocking on its head.

Also of note is the money-saving Realtek Audio/LAN combo.  We know that Realtek does a discount when these are bought together - the LAN isn't always as configurable as the Intel versions and can use more CPU power too, but for a consumer board, it can be considered acceptable.  ASRock are introducing XFast LAN to their line up, which offers a software solution comparable to the Bigfoot NIC.  XFast LAN is discussed later.

Despite this being the Extreme6 model, we're not getting one of the crown jewels of the ASRock product packages of late - the USB 3.0 front panel bracket and SATA drive holder.  What we get instead, although not price comparable, is an audio cable for a motherboard to monitor.
