Personally I think the priority is to upgrade them if they will make a noticeable difference to what you get from your time playing the game. They don't come close to helping me earn for upgrades so seems pointless.
It seems the chief argument for max upgrading resource buildings is to 'help the community' ie, players other than yourself. Nice idea as that is, I think the incentive needs to be more beneficial for the person actually spending time and workers etc than for making raiding more profitable for other players.
The majority of players are going to 'let's just keep raiding to get what we want', because the free resources are negligible.
Even the game loading screen recommends that for advanced civilizations, forget farming and rely on raiding.
My resources are at about GPA level btw and highly unlikely to change any time soon!
