Just a quick one? I would like to know what the 3rd slot for a pci-e graphics card is for in this sli mobo. As far as I know sli gaming only allows for 2 GPUs yet theres 1 more slot in a different colour in between them?
Well, there are actually three PCI-E x16 slots: two for SLI graphics cards and the third is intended for use as a physics card at x8 speeds. Presumably you use a third graphics card for this purpose.
u could also insert a pci-ex1 or x4, or x8 card in the third slot and yes they will fit the 1, 4, 8 are just not as long but will funchion in the slots at full speed.
