The features alone cover the difference. Do you realize how archaic asrock or anyone elses software overclocking is in comparsion to asus's? No you dont. Every other board manufacturer has presets where you press a button in the bios, the asus goes through an actual stress test and varies the voltage to the clocks you are running.
Example:
Asrock max overclock preset, 4.4ghz 1.4v
Asus max overclock with AU suite, 4.6ghz with 1.35v. While keeping every power saving feature on as it should be done, many times the auto OC presets on lesser manufacturer boards used fixed volts or even turn speedstep off. You really havent a clue how far advanced asus is in this respect.

Not only are you wrong on that, you are missing out on one of the best features of asus motherboards....the fan headers are able to control RPM even on non pwm fans. No other board manufacturer can do this, it legit negates the reason to own a fan controller. You know nothing about your own motherboard, do you think you are in a position to be giving advice to other people on the matter?
