From a personal point of view of somebody who just upgraded to an AMD-based desktop from an Intel one, the CPUs work great. It's the software support that feels half-baked. Enabling memory integrity blue-screens my computer. I need to update the chipset drivers every month because AMD is still dialing in their scheduler and frequency scaling over a year after release, and the idle power usage is inexcusable.

AMD's performance is fantastic, which is why I was fine getting it for a home gaming desktop, but I'm not sure I'd be willing to pull the trigger on AMD on an enterprise server buildout. Intel still simply (actually or otherwise) feels more reliable.
