Comparing one hd6990 and two hd 6970 crossfire?

Im trying to figure out whats best for me. Setting up a 3 monitor gaming rig using an I7-2600k set up.

I wonder how the specs would look comparing the following info with just one hd6970 as to what two would look like?

Or even two 6950's crossfire compared to 6970 crossfire or just the 6990?

UGH.. this is he hardest decision I have to make.

2 HD 6950s in CF will perform close or maybe a little bit lower than HD 6990. HD 6970s in CF will perform better than a single HD 6990. and as long as you're going Eyefinity, i would suggest you to stick with the HD 6970s in CF, just make sure your PSU is capable of handling it.

For 3 monitor setup it's called nVidia 2D/3D surround, requires 2 GPUs in SLI so a single GTX 580 wouldn't work.

I can assume this mb will work for crossfire of the 6970's? GIGABYTE GA-Z68XP-UD3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

I keep reading that not all games benefit from crossfire. That would suck if Im building this specifically for bf3 and it wont?

even the BF3 beta builds supported crossfire, and the scaling will only improve.

well, all the modern games benefit from CF and SLI, most of CF / SLI issues are related to drivers and hardware configurations.
You said you're going to Eyefinity, and no way... you need a CF setup in order not to experience a lag of FPS when running such games in a such higher resolution 5760x
if you don't wanna feel the hassle from CF / SLI issues so a Dual GPU is your best option.

So the issues with crossfire are driver and hardware configs. That seems like it would be easy to google, find and correct, right?

That's what i see so far, according to benchmarks all the games benefit from CF with a maximum 40% increase in FPS

When Tomshardware reviewed both GTX 590 and HD 6990, they recommended a pair of GTX 570s over a GTX 590 and a pair of HD 6970s over a HD 6990.

Toms recently reviewed a round-up for some LGA 1155 MOBOs, you can check them and pick up the recommended one.
For SSDs i don't have much experience with it, as also i'm trying to pick up one for me, but the most i have been searching recently is Corsair Force GT and OCZ Vertex 3, they both have the same outputs and got great reviews
