Having finally seen a 5800K perform, I don't really think the CPU element of it in gaming is as weak as most make it out to be, it is capable of handelling lower mainstream cards, though its rather pointless at this juncture. Dual graphics mode delivered well above expected performance at 1080 resolutions. I believe the new A Series Athlons will be a hit, more CPU power but on the FM socket, designed to run mainstream level GPU's without detracting from purpose.
Knowing that SR A-series will run on FM2 socket, a Athlon based A-Series running CFX 7770's could deliver unrivaled low cost gaming performance at lower cost that a mainstream i3 rig.
