Looking for a Z77 with 16x/16x pci-express

So i'm looking for a motherboard that will run crossfire OR sli with two video cards at 16x each.

It would be awesome if its a decent overclocker as well. What's the best option?

You are going to want a board with the PLX PCIe 3.0 bridge chip.

Read this review from Anandtech. They review the Z77 boards that have this chip.

Unless you're doing quad-crossfire/tri-SLI, don't bother.

If you want more PCIe lanes, you go X79, not Z77.

i'm asking about the z77, not the x79.

Right, time to switch platforms if you really need more lanes.

And no matter what, the cards will still only have 16 PCI-E 3.0 lanes to communicate with the CPU, because that is all the CPU physically has. Better to have the cards run in 8x communicating directly with the CPU than to run at 16x with a chip in the middle, especially since no single card can actually saturate a 8x PCI-E 3.0 lane. They're only just barely starting to saturate PCI-E 2.0 8x (equivalent to PCI-E 3.0 4x).
