Maybe I'm just lucky, but I went for the "reworked" Intel SC2600CP dual E5-2670 combo from Natex back in November for $350 shipped and it has been 100% stable with the original circa 2011 BIOS it was delivered with and now with the latest BIOS. It's ran right out of the box, has never crashed, hung or locked up, and runs great with a mini GTX 1060 installed in the full-size slot 6 (the top slot). Gaming is actually very smooth since there's very little FPS loss running at PCI-e 2.0 at x8 vs. PCI-e 3.0 at x16. Refer to the link below for details on PCI-e scaling.

It's powered by a Supermicro 665W PSU I picked up for $38 at Microcenter. Libby Hackonson was very helpful during the buying process and Michael Biglen answered my questions regarding doing the BIOS flash on the "reworked" Intel SC2600CP motherboard. The combo cost less than a single i7 6800 CPU without any motherboard or RAM had I decided to go for a single-socket LGA 2011 V3 rig. So I'm very satisfied with my Natex purchase.
