In my case, I want the 8 SATA ports. The high-end ASRock seems to have them too at a lower price point. However, right now, seems like Newegg and Amazon have neither my ASUS nor ASRock (or hardly any others).

I suppose the MB manufacturers held back production to see when and how things went. I hope the boards released in the next few weeks have the BIOSs mostly fixed. If so, waiting may pay off.
