Depends on what you're planning to do with the rig.....
Do you OC? Are eco friendly? are you into changing the different settings of the processor, ram , multipliers etc etc?
If the Answer to all the above is yes, then, these utilities let you change stuff that is needed to touch high processors and ram speeds, inclusive of currents and other little timings....
If you don't usually fool around with such specification, then I'd best just Uninstall them so as to avoid a big time mess up...
And if you need more info on these utilities, you'll have to download the Asus User manual if it didn't come with the Board to go thru each and everyone of the utilities settings and capabilities....
