ASRock 990FX Extreme9 review
 

When you compare the ASRock 990FX Extreme9 to previously tested AMD 990FX boards, you can see that the new ASRock board is one of the most comprehensive boards on the market. Whether you will actually use eight USB 3.0 and eight Serial ATA 600 on an AMD board is another question, but if you're in need of high-end Socket AM3+ board, this 990FX Extreme9 is a great option.
