Question Why and When to replace O2 Sensors?

Will replacing the O2 Sensors in my car help the performance at all? I think that the ones from the factory are still in it, and at 85k on the car would it be a good idea to replace them?

Won't help performance since they aren't used WOT, but they will help gas milage and regular driving.
