Asus have always been one of those brands that wants to cater for every market, and that's not a bad thing, certainly not. It gives the end user a bigger selection to chose from and lets Asus identify their customers, meaning that can then manufacture their products to suit the end user more. This is why Asus have made many boards ready for the Intel X79 launch, and with different boards aimed at different markets, it allows consumers to spend their money more wisely.

Not everyone can afford a Rampage IV Extreme motherboard with all of the bells and whistles, and not everyone wants to, as half of the features may be worthless to you, especially if you don't plan on using LN2 or voltage modding your components, and the simple P9X79 Pro and Deluxe boards offer a bit of what you want, but is missing some vital features, especially when it comes to rock solid stability, especially when overclocking.
