You know the more I think about this the better this change seems to me. The original X670 and X670E distinctions were already pretty useless if I recall correctly and by basically moving up the B650E spec to X870 they removed that useless spec. Only thing left open for question is what happens with the gap now, are they just going to pull the entire stack up or will there simply be no B850E? Also granted I'd rather have seen a larger improvement from the X670 and X670E spec than them putting a previous mid-range chip into the high-end but at least there is some form of sensible difference between X870 and X870E, albeit the differences to the previous gen are suffering a bit from this weird diagonal upgrade.
