Motherboard: * GIGABYTE 970A-DS3P AMD 970 ATX w/ Ultra Durable 4 Classic, On/Off Charge, GbLAN, 2 PCIe x16, 3 PCIe x1, 2 PCI
I would be inclined to go with a Gigabyte GA-990FXA-UD3. The higher chipset would mean better CPU response, less chance of a bottleneck with the power of a 6 core CPU... and not much difference in price, either.
I agree, but these are the only options they offer:
ASUS M5A97 LE R2.0 AMD 970 ATX w/ GbLAN, 2 Gen2 PCIe x16, 2 PCIe x1, 2 PCI (Pro OC Certified) [+29]

MSI 990FXA-GD80 V2 AMD 990 ATX w/ Winki 3 OC Genie, GbLAN, 4 PCIe x16, 2 PCIe x1, 1 PCI (Extreme OC Certified) [+131]
And as you can see, the other motherboard is $71 more. That's pushing it. I'll see if I can suggest this without having my wife ask me sweetly for any nearby cutlery, but I'm frankly doubtful.
