X299 boards show up for preorder at Newegg
 

We were very excited when we heard that the Skylake-X-derived Core X-series CPUs would be significantly cheaper on a per-core basis than the Broadwell-E series that preceded it. The pricing on some of the chips toward the bottom of the series is downright reasonable—particularly the 6C/12T Core i7-7800X at $389. We were hopeful that the price pulldown would extend to the X299 platform itself, but we weren't sure what pricing on LGA 2066 motherboards would be like, at least until now. Newegg has 16 motherboards up for pre-order. Spoiler: they're a little pricey.
