Asus P8Z68 Deluxe Gen3 PLX Chip

Does anyone know if this motherboard has a PLX bridge? It is not listed in the specifications, but I believe other Asus deluxe boards have had it in the past. It is my understanding that the Pro version of the Asus Z68 motherboard does not have a PLX chip, so if too many PCI/PCIe slots are full, certain features are disabled, like USB 3.0. I have a triple-slot graphics card and a soundcard and I want to make sure I can put them both in the motherboard without losing any functionality (such as disabled or slower usb 3.0 ports). I might also add other PCI/PCIe cards or a second graphics card in the future. Does the Asus P8Z68 Deluxe Gen3 have a PLX chip that would make this possible?

Thanks!

In case anyone is wondering, I downloaded the manual and it does show a PEX 8608 chip on the diagram of the motherboard. There is also a PCI bridge chip on the motherboard.
