Lifetime? As far as I know as long as you do it properly with sufficient cooling to make up for the additional heat the life of the components shouldn't be affected much at all. Anyways, it's really hard to judge how long a component will last even w/o overclocking, they'll last you long enough until your next upgrade I suspect.
