The board we have today is the Z87X-OC which omits the bridge chip and Liquid cooled VRM area in favor of a much more affordable cost. The tradeoff however does mean you give up the ability to run more than two way SLI or Quad SLI with two dual GPU cards, but since AMD does not limit crossfire to a specific lane width you can actually still run 4 card crossfire on this board but the lower three cards will be running at x4 PCIe which means there could be a bottleneck there.
