I bought and used the Gigabyte board you linked, but it runs warmer than most boards I've seen. It's also suggested that its BIOS isn't so hot. As an 980FX Gigabyte board owner...yeah, Gigabyte has had some BIOS issues with their newer boards it seems. I suggest this board:
As for the CPU, if Newegg had stock of the X3 740s, I'd suggest that, as their unlock rate is exceptionally good. If you can go with $320 total price, then get a 1055T and the above motherboard..it works fine. The 1055T runs $180.
Or, you can get this: A 3.1 Ghz quad Athlon II for $115.
If you don't like those options, the 955BE is my other suggestion.
