A:Answer Overclocking a GPU can cut down its lifespan some, but that's purely determined by just how much you overclock it by and how often you play on it, and how long.
You don't have to overclock your GPU if you have one that allows for it to be overclocked. It'll give off much of the same performance, if not better when compared to a Founders Edition card, which usually does not have room for overclocking. Typically it is built for better cooling capabilities which is designed to counteract the temperature increase that is bound to come from overclocking.
