my specs

cpu - amd fx 4170
gpu - asus radeon hd 7770
ram - Kingston 8GB DDR3 1600MHz HyperX Memory (KHX1600C9D3K2/8G)
psu - powercool 750watts

You only need x8/x8 PCIe 2.0 and even if needed the x4 PCIe 2.0 can work with minimal frame loss; see - http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI... (note: the article was using an Intel IB CPU).

Everything you posted above works on the Gigabyte GA-990FXA-UD3.

So it comes down to budget constraints on the MOBO. The ASRock 990FX Extreme3 would be my choice, again the AMD 990FX chipset is the best choice.
