You should do it now if you are able to, like for example if you Spiritbond your current gear before replacing it. Even if you don't need it they are noticeable boosts so there's no reason not to as it will just make you faster/more efficient.

It just doesn't impact you negatively so why not do it? Just don't worry about going out of your way for it unless you manage to get a piece of HQ gear that can last a bit longer.
