While Asus retained the "traditional" blue/white colour scheme for the X79 WS board and the later X79 E WS board, the Asus Z87 WS motherboard took the gold/black colour scheme from the mainstream Z87 product stack and coupled it with more subtle (non-gamer) work station style heatsinks.
Although the gold colour looks better in reality than in pictures, it is still a major departure from the conservative blue/white colour scheme which the work station market has become used to. That said I believe that these work station boards are of course also aimed at the gamer, due to their ability to do 4 way SLI/CF.
In my market, the Asus Z87-WS motherboard is the least expensive board to have this ability by a large margin. On a side note, why is the Sabertooth Z97 board given the suffix Mark I? Does this mean that we can expect a Mark 2 as a subsequent revision?
As far as I remember there has only been one Sabertooth board released for each chipset generation?Edited by Reworker - 4/20/14 at 2:55am
