Can you recommend a motherboard for me?

Hi. I'm going to have a i5 2550k (1155 socket)
And a 7970, yes the 7970. The $600 new HD Radeon.

So I was going to get this, the ASUS P8Z68-V PRO/GEN3: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131790
But then I thought for the future, and I will be crossfiring two 7970's sometime 2014. I found that the speed is x16 for one card, and x8 for each when using dual card. (That's Crossfire, right?)

1. I couldn't find any x16 dual card on Newegg. DO THEY EVEN EXIST!!?

2. Will this mobo I have be fine, and does the (x8, x16, etc.) even matter? Is it relavant. For performance.

P.S. Is this clear enough?

    Looks like a 16x/8x setup doesn't affect performance.

    Take a look at this MB: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131760
  6. i also look at that mb but it say PCI Express 2.0 x16: 4 (x16 or dual x8 or x8, x16, x16)
    so for dual only run x8... is it?
  7. Then He should go Sandy Bridge-E X79 chipset MB. It supports 16x and 16x PCIe 3.0
  8. ASRock Z68 Extreme3 Gen3
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813157271

    if you really want to do that 7970 justice, get an ivy bridge processor when they come out next month for pci 3.0

    or just get a 6970. . . .
