Yes, Der8auer in the video even states that his was "pretested", or one of the better Bins. However, I would guess that even lower binned chips will likely reach 4.5GHz. I also agree that X299 is still horribly priced, but for those who want a 6/8/10/12 AND high single core performance, Intel is their choice (albeit the cost per performance is likely worse, especially concerning increased cost of the X299 chipset).
