Though this is an old article i felt completed to comment. Having to pay royalties on a motherboard is obsceen. The obvious choice of where to place an additional SLI or Crossfire tax is on the graphics card itself. In that way, you choose which way to go when you buy your graphics card and if that multigpu tax is gpu card based, you pay appropriately as you increace the number of gpus in your system. To place a multigpu tax on the motherboard itself and then screw you end consumers by artificially limiting it yo AMD or Intel or in some other non competative way via is just a scam foisted on us all. SLI and Crossfire motherboard certification is just a marketing scam. Set up the SLI and Crossfire specs in an open way (as part of PCIe spec) and be done with it. If manufacturers stuff up their implementation, well they will loose business and this is how it should be.
As is, both crossfire and SLI motherboard certification is a money grab.
