I find AMD's desktop excavator architecture interesting.
It may not be terribly popular considering how many Intel enthusiasts there are on the forum and the fact that ZEN is hitting the market.
However, I am really digging my AMD 845 Carrizo 65w build.
I built a VR ready, low power consumption, 4k capable SFF gaming rig for under $1,000 using AMD FM2+.
I'm routinely hitting 120+ fps on my favorite online multiplayer game which is amazing considering the price point and that is SFF.
It's true that most of the performance boost has to do with upgrading my GPU from a the GTX 750ti to the new low power, higher performance, GTX 1060 but the Carrizo supports this build fantastically and at a lower price point.
