I would say that it is worth the extra money to get a CPU that runs reliably at the advertised speed, and where you do not void your warranty.
Because of the way processors are batch-tested for speed, some may work fine when over-clocked, others will not. An overclocked CPU may also not last as long as a 'proper' one.
I don't the risk as not being worth it, also given the small speed increase.
