Every overclock is a trade
An overclock is not a straight power increase. It moves a stat from one column to another, and the question is whether the trade suits how you already play.
Read the downside
Look at what you lose before what you gain. Lost magazine size or added recoil changes a weapon more than a damage number suggests.
Match it to the weapon
Start from the weapon’s base stats in the equipment database, then judge which weakness you can live with.
