Mobo for Double 6970's

Hey there everyone, I'm building a new rig and looking for a good mobo which would be suitable to my needs.

In terms of GFX output, I'm looking at 2 6970's Crossfired DVI-D(DL) to a Hp 30" Monitor running at 2560×1600 (1600p).

First time building a gaming rig, so bare with me if I miss out some details. xD

System Board needs to support:
Intel i7 980X processor/12+GB of DDR3 RAM/3.0 USB (at least 2 ports)/PCIE-2.1+ 3-6 slots.

I was wondering in regards to graphics cards whether or not plugging them into a x16 or x8 PCIE slot would make a difference performance wise, and if lets say my mobo had 1 x16, and 1x8 slot would there be a loss of performance when Crossfiring them?

Thanks for you time and help :pt1cable:

I'm assuming that, with your extremely high-end processor you're going to go for a high-end motherboard.

ASUS Rampage motherboards are a gamer's dream. Handles quad-crossfire should you choose to, handles 24GB of DDR3-2200mhz RAM, has USB 3.0, Many MANY overclocking options, everything a gamer could ask for.

That rampage is omg, pure win and I love it, i want to have its babies.

4gb ddr3 ram in each slot, 2 6970s and i think im set.

Once the 6990s come out, seeing how this has 4 PCIE slots, would it possible to have CrossfireX support 4 of those badboys for a grand total of 8 gpus?

I know it would be a huge waste of money, i was just wondering if it was possible.

Indeed it would. The HD6990 is most likely two Cayman chips (either HD6950 or HD6970) on the same board, allowing for Quad-Crossfire.

I usually recommend lowering specs on some stuff, but 2 6970... you will need all the processing power available with a core i7 and probably 2 16X lines.

You can use 6GB of memory instead of 12GB.

6gb of memory is more than enough.

I will never understand why someone would pay $360 for a mobo, especially when a new socket is coming out. I never pay much more than $100 for a mobo, and I'm on the 4th year with the one I have, a more expensive one would have done nothing for me in these last 4 years.
