Why no new AM3+ Socket and a new Chipset? Asrock for instance make fine Boards with great Features, and you were compatible with next Generation Processors.

And they are not so expensive like similar Boards from other Manufacturers. I build a Computer with one of these Boards and was amazed about the equipment of this Board. The Performance of the Chipsets in Crossfire was the same, the 890GX have the same amount of Lanes for the Grafikcards like the 790x Chipset.
And you get a Grafik Chip for free.
The Maimboard is the Basement of your Rig, all other is replacable without a lot of Work.
