DC does a variety of things, it lets you cutomize rgb lighting, switch power/battery profiles, controls special keyboard keys "Fn" function, does allow a very limited function of overclocking both cpu and vram and a bazillion of other thing any self respecting gamer does not care about. I would generally advise against using any "all-in-one"/"one-click-go" apps, they underperform and do more damage than good. As to ur question it depends on what do yuo actually want to do, for example you can manage ur battery/power profiles urself via windows control panel without having to run a unnecessary app in the background and you will end with much better results in overclocking following any on-line guide rather than this. As to rgp lighting you have to experiment, mystic light is a default msi app but I found that gigabyte rgb fushion does the same job perfectlyfine in my config. There is one thing probably no other app will do and that's the custom keyboard key function.
