Everything looks compatible but you have to check the memory like I said earlier. And as far as the memory goes take a look at G.Skill. Here's a

The ASUS I linked to is $139 and the RAM is $99.
You can compare the three budget friendly ASUS boards to see what the difference is

If you think that's still too much for the MOBO Gigabyte does make fine motherboards. So don't necessarily just go on my say so. Do your research.
