PCI-E 3 WAY SLI Z77 Board Max Lanes!

Looking for recommendations on a high end board that can take 3 PCI-E GTX 670 PCI-E 3.0 cards at the highest possible rate. 16x/16x/8x would be fine :) This setup is going to run 5 screens with unique picture on each for a sim. The screens are 65" so not small!

Going with the Z77 chipset as I need to use RST 11.2 (or 11.5 if memory leak issue is patched or next driver version to fix) for SSD RAID 0 Trim support (data and program size for sim is hitting 512GB, so using two 512 SSD's in RAID 0).

A lot of the new boards I am seeing are only doing 16x/8x/8x for 3 way. I know PCI-E 3.0 is supposed to be double the bandwidth as 2.0 (IE: 8x on 3.0 is 16x on 2.0 - or am I wrong?).

Not worried on 'bang for the buck', these needs to be super fast and rock solid stable. Going with the newest 3rd Gen i7 as CPU.

    The PCIe 3.0 lanes are straight from the CPU and can only do either x16 or x8x8. The third x8 slot would be from the IO Hub's x8 PCIe 2.0

    If you want to do x16x16x8 all with PCIe 3.0, you would need go get an LGA2011 SB-E CPU which has 40 PCIe 3.0 lanes.

    Thank you for the reply! Just checked into it and seems the best route, hence how I am seeing x79 boards with more lanes. Main issue here is no TRIM support for any chipset supporting LGA 2011 on SSD RAID 0. I keep reading how x79 is getting it 'soon' but you know how that works out.

    So stuck :/
