Yeah, the scientific approach would be to run a before and after test with consistent runs. That is going to be hard to do.
I say just run it like normal and see how it does. And even though it doesn't offer a tangible performance difference, you can at least be secure in your mind that the existing caps aren't being worked as hard.
