      Yes, I know the monitor sucks. I still have it only because it's touchscreen and therefore good to keep on my desk with the soldering iron and other tools that are best kept away from keyboards/mice. Issues: Other than the PCIE bandwidth with that particular adapter, I noticed that the sound over HDMI was spotty and would cut out. gfycat showing a little Witcher 3 running 45-50 FPS 1080P on "high" settings: https://gfycat.com/TalkativeSlushyArcherfish YouTube video showing the "high" settings, a little more play: https://www.youtube.com/watch?v=5LSkv8VfEJs  Valley benchmark showing the NUC without the eGPU, score 1126 http://i.imgur.com/rQTQd8C.jpg Valley benchmark showing that same GPU in a Haswell i5, score: 4986: http://i.imgur.com/Z2070Hj.jpg Valley benchmark showing that same Haswell i5 system without the GPU, score 415: http://i.imgur.com/mNBqaBT.jpg PCPartPicker of the Haswell box, for the sake of comparison: http://pcpartpicker.com/p/y2V7Yr Valley benchmark from the album, score 2504: http://i.imgur.com/CksiPJI.jpg  Lessons: I need to find an M.2 to PCIE adapter that carries more/faster lanes, but really only losing 50% performance using only TWO LANES of PCIE 1.1 bandwith shocked me. I expected to lose a whole lot more. Also the Intel Iris Pro in the NUC blows the doors off Intel HD graphics in the i5 4690k. If not for the tremendous amount of power lost to the M.2-PCIE bottleneck, this would certainly be a playable level of gaming at 1080p if I can build an enclosure for it. For now, the GTX 970 is returning to the Haswell system and I am going to continue to use that as my steam machine until either I can build something smaller/quieter (too bad I built it before Bulldog was available) or an affordable Thunderbolt 3 eGPU enclosure hits the market. I might try to get the 3D printer working again and make some sort of enclosure when I get the speed worked out.

Don't buy: The alleged 4-lane m.2-PCIE that didn't find the card at all so don't buy it: http://smile.amazon.com/PCI-Open-Back-Card-Adapter/dp/B0182NRGYO Don't buy this either.
