That board should be good for 6 single chip GPUs.
I have a MSI Z77-GD65 that will only work with 6 cards.
I also have an MSI Z77 MPower and an MSI Big Bang Xpower X58 that both run 7 7970s.

ok cool, wow 7 cards? i was thinking i'd use the 7th slot for a wifi card, wanna avoid cable as much as possible.
mind posting pics of your build? how are you dealing with power? i'm thinking of getting http://www.citilink.ru/catalog/parts/powersupply/668120/ to power 6 7950s, is it enough or should i split the power between two smaller ones?
Take a look at this post for an idea of how most of my rigs are set up.

6 cards is easy to set up, 7 is more of a bitch. You could always try for 7 and use a USB WiFi adapter instead of PCI-e. Some boards will disable a PCI-e port when 6 ports are in use, so you may have to use a USB adapter anyways.
For the power supply, I would avoid that one or anything else Thermaltake. Personally I only use Seasonic (Silverstone 1500w in picture died powering 5 7950s and Silverstone won't honour the warranty) , you simply can't get any better than Seasonic units. Splitting smaller PSUs is the way to go.
Coolermaster has started using Seasonic to make their new V series power supplies. They are TOP notch, and based on Seasonic's latest KM3 platform. They are rated Gold, but are actually Platinum. I don;t know about Russia, but right now you can pick up a V1000 for 160$ after mail in rebate which is a smoking hot deal for that kind of quality.
Coolermaster (Seasonic) V1000 review: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=344
For power, I've run 30A 240v circuits where I need. SOOOO much better than running power supplies on 120v.
Here's what my power supply distributions look like:
1x: Seasonic X1250w + 1x: Corsair CX 430 powering 6x 7970
1x: Seasonic Platinum 1000W + 1x: Seasonic X850 powering 7x 7970
2x: Coolermaster V1000 powering 7x 7950
1x: Seasonic X1250: 5x 7970
1x: Seasonic X1250: 4x 7970 + 1x 3930k for Primecoin
Plus I have a spare Seasonic X1250 for another rig that I'll be building eventually.
My 7950s average 680KH/s while pulling 300w @ 1.09v
My 7970s average 740KH/s while pulling 220w-250w @ 1v-1.1v.
If you're using powered risers, only power them with the primary PSU, same goes for motherboards with an extra PCI-e power connecter.
