Why are SLI compatable AM3/AM3+ motherboards way more expensive than Crossfire motherboards?

Basically, If I want an SLI motherboard, I have to spend more money, why?

Crossfire motherboard, for AMD GPU's: http://uk.pcpartpicker.com/part/asus-motherboard-m5a97ler20

SLI motherboard, for nVidia GPU's: http://uk.pcpartpicker.com/part/asrock-motherboard-990fxextreme3

I know that the chipset in the boards are different, but should that make that much of a difference in price?

they need to use a plx chip in order to switch the pcie lanes so the component cost goes up.

OK thanks, that explains it.

I imagine there's also licensing fees involved with implementing SLI, whereas CFX is AMD's own technology.

ah yes, I see the logic in that, thanks for the comment.
