Hur många grafikkort kan man köra på detta mobo?

Saxat från en testsida på internet: The ASUS Maximus III Formula has three PCI-Express x16 slots but due to the fact that there is insufficient lanes provided by the platform, these slots only operate at 8x8x4 when SLI or Crossfire modes are in use. The bottom white PCI-Express x16 (x4 electrical) slot is badly placed in my opinion. The problem is that cards with large cooling solutions just won't fit here in many cases because those chassis do not have the appropriate clearance to allow the card to "hang" off the bottom slot. This isn't nearly as big a deal as it would be on an X58 board as the X58 boards support 3-Way SLI or CrossfireX with three cards. The P55 Express chipset based Maximus III Formula does not. The only multi-GPU solutions supported here use only two cards.

Crossfire med tre kort eller grafikkort för multiskärm (ej spel).
Sedan finns det ju en uppsjö av andra PCIe-instickskort än grafikkort som man kanske vill ha plats med, kontrollerkort, ljudkort, NIC, TV-kort, SSD-kort, listan är lång.
