Vega's *Heavyweight* display and computer; edition 2012

Read about the asrock x79 board which has a pci-e 3.0 switch in it (PLX PEX8747). So yeah no reason this couldn't be used in an IB board to give you all the lanes you need, just a question if nvidia refuse to support it, but the article claims that this board at least does support quad sli:

Ya, that board looks pretty sweet. Not sure though how much performance would be gained with quad 16X speeds slots PCI-E 3.0 with the PLX chips versus native quad-8x PCI-E 3.0 with the Rampage IV Extreme.

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.
