The picture at the start of this review shows a box where artwork on the front mentions Thunderbolt twice. But I searched for the GA-X99P-SLI at various online retailers, and found mostly listings which showed slightly different box artwork, with no mention of Thunderbolt, and which did not mention Thunderbolt in the specifications. I don't know what the story is, but it seems to raise the possibility that if you order this board, you could receive something different than the board reviewed here.
