Will this motherboard bottleneck 2 7950s

I am wondering if this motherboard will bottleneck 2 7950s http://www.newegg.com/Product/Product.aspx?Item=N82E16813130653&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

The reason i am asking this is because it has one pci express 3.0 x16 slot and a pci express 2.0 x4 slot which i am primarily worried about with the bottleneck

Well I'm not 100% sure but I'd go with something like this just to be safe http://www.newegg.com/Product/Product.aspx?Item=N82E16813128546


that msi board wont realy bottlenecking in gaming at the moment, the only problem with this board is, its has 2 pci-x16 slots, but only one is  3.0 and the second one is 2.0.

i think if you gonne crossfire, they both gonne use 2.0, but that doesnt seem, as a bottleneck to me...

but better to spend a bit more for a more decent board.

like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130645

It will bottleneck the 7950 in the PCI-E 2.0 slot @x4, it would be best to go with 2 PCI-E 3.0 slots at x8 or PCI-E 2.0 slots at x16

if your going to ger another board try to get a Gigabyte D3H or UD3H, solid boards, and they have a Supplimental power connector to help with crossfire

if you are looking for a cheap dual graphics board, get the MSI z77a-g45.

i have both the g45 and the g43. they are board great boards, the g45 supporting SLI/Crossfire, and the g43 just supporting crossfire. i bought them both for like $115 at tiger direct, but just get the G45, its btter.
