I am designing a game heavily influenced by the minecraft style but in a limited world (not an infinite world), at what point do I need to be worrying about chunking instead of using cubes?
I have googled a bit on it and found a few tutorials, but I was wondering if anybody had some tutorials they could recommend?
If you have more than a few dozen or a couple thousand, depending on hardware target.

Yeah Eric is right. If I were you I would make in the settings page an int variable that changes the distance of when you should start chunking.
My target was mobile devices. I am assuming from that response that my 4K target I had in my head was too high 
I guess that means time to learn chunking.
