I had hopes for the ASRock Z77 Extreme9 supporting Quad-crossfire at quad-8x PCI-E 3.0 because of a PLX chip but seeing this new picture I have my doubts (cover says 3-way SLI):



It seems nVidia will never allow Quad-SLI on anything but X79 this year.

So I basically have two options, go with the R4E which is a known quantity and good board with quad native 8x PCI-E 3.0 or wait for this ASRock Extreme11 which has quad-16x PCI-E 3.0 with PLX chips that add unknown latency and performance.
yeah - not sure why asrock went with the pci splitter on X79 to be honest. Maybe they're just look for a differentiator to compete with Asus. That Z77 pcb does say 4 way SLI though even if the heatsink says 3 way sli. Bear in mind that it also says z68 gen 3 on the south bridge, so I wouldn't trust the heatsinks - looks like they just reused the heatsink for the prototypes.
