I'm putting some new parts into my computer, and was looking into grabbing a new motherboard. I was originally trying to decide between the ASRock Extreme4 and the MSI Mpower. I was leaning towards the Mpower due to the fact that it had six usb 3.0 ports, versus the Extreme4, with four 3.0 ports. However, I'm unsure if its worth spending the extra money for just two more 3.0 ports. Does the quality of the Mpower over the Extreme make it worth the buy?
