I wouldn't call it fake because that layout doesn't match any Maximus Impact so is at least a totally different board.
Not sure about the DVI connector though - MI7 and 8 went HDMI and DP (such a sexy back panel now with nothing sticking out
), unless there's some limitation to the IGP. That's the only thing I do question though - the existing FX chips don't have IGP, and why would Asus make an Impact board for an APU? Will Zen FX have IGP?
I'll wait until a proper confirmation, but I don't see any reason why Asus wouldn't do a Zen Impact, and this just could be a concept board to get interest.
