I know this is way outside the scope of this thread but I just thought I'd mention that with Mac OS X Mavericks this board works really really well. No manual file editing or forum scouring for kexts. Sound, Networking, Storage (even the Asmedia chips) USB 3.0 = all works with installers like Tony's Multibeast post-OS X Installer. This is even on the very latest BIOS from Asus website. No DSDT necessary unless you want speedstep and turboboost but I expect most of us here will be overclocking anyway.
