CPU could be great, but Motherboards still haven't caught up

Summary: I bought this CPU because it's nearly top-end fast, but considerably cheaper than the 39xx series. However, there is a gotcha: LGA2011 X79 motherboards were mostly released in late 2011 for the 39xx chips and didn't support the (as-then) unreleased 3820. It was only supported in BIOS upgrades during Mar-Apr 2012. You have no way of knowing what BIOS is in your mobo until you assemble a system and attempt to power it up.
