In the past and still today Asus have some of the top rated mobos, so as for the maker, good choice, as for the specific boards unfamiliar with them.
For the DD it is a concensus, that reformatting is the best and most stable route in the long run. Of course you will have to backup all important data, that is always a necessary pain.
You don't have that much to lose however in trying a simple DD switch and see how stable the sys is. And if you find too many lockups or blue screens then you always have the option of reformatting and reinstalling at that point.
Houston! Be aware! There is BS in the view window!
