How tightly should I screw down the top cap?

Changing out my stem and watching videos, most people say only to turn the allen key until you meet resistance, then maybe give in an extra 1/8 of a turn at the most. I did this, and don't feel any play in the headset (though this is my first time).

My bike came assembled, and when I first removed the top cap, I had to use a good bit of force to loosen it. There is no way that they stopped tightening when the allen met resistance.

Now I am not sure how tight to make the top cap. Don't want to damage anything obviously.

This will set you up:

If you're impatient, jump to here:

But watch until the end. Basically, just snug up, check for play, tighten 1/8 turn more, check for play, etc. Then tighten up the stem bolts.
