ASRock X79 Extreme6/GB = LGA 2011 Mainboard + PCI-E x1 Card
 

Today we are going to talk about not the very top, but also not the very junior model from ASRock. However, we can't call it mainstream either. It is a very feature-rich mainboard that tends to be closer to the flagship models. The "GB" letters in the model name are an abbreviation from "Game Blaster" - a complex expansion card that combines the functionality of a network and sound card.
