First is to squeeze more performance out of a cheaper processor, to match (or on par with) the performance of a more expensive processor. In other words get more performance at a cheaper cost . Second is to "extend the life" of the processor (no need upgrading for another few more years). In other words, getting current/new performance with older/yesteryear's processor.

Caveat: Better cooling required usually (e.g. better CPU cooler or HSF) and beefier PSU recommended.
