Again, please stop spreading FUD.
USB 3.0 is native to the chipset, yes, but not the CPU, as the CPU has nothing to do with it.
The current issue with ALL LGA-1155 7-series boards is that we don't have full support from Apple yet and it's not expected until 10.7.5 or Mountain Lion, hence why people are having problems. It has nothing to do with incompatibility between CPU's and motherboards, as Intel has made both platforms forward and backward compatible.
And on top of all that, HD 4000 graphics doesn't work yet, so why would anyone consider it right now?
