OCC has published a new review of the ASUS M3N-HT 780a SLi

So what do we say about the ASUS M3N-HT? It performs as well as, or sometimes better than, AMD's flagship chipset, the 790FX. The scores were marginally better for the newer 780a chipset. The option for AMD processor users to finally have a great choice of motherboard chipsets and designs is a plus. No longer are you stuck with certain options, like only being able to use Crossfire. Now you can run that NVIDIA SLi rig with your Phenom X4 and kick some serious butt. The ASUS M3N-HT has many upgradable options such as the ability to run triple SLi if you have the cards available, or Dual SLi if you do not want to spend that much on GPUs.
