Question about "Superclocked" and "XXX" cards

A question about cards labeled "Superclocked" or "XXX": Are they the exact same cards as their "normal" counterparts, just factory overclocked? (i.e. Is an 8800 GTS Superclocked just a factory overclocked 8800 GTS) If not, what's the difference, and if so, is their any advantage to paying $30 extra for the "superclocked" version?

Thanks!

In most cases, they will be identical, the same way as an e6400 is identical to an e6600. The e6600 just performs better and spec'ed higher because of. This isn't to say that the e6400 will not achieve the levels of the e6600, it's just the way the factory determines the processor spec.

Sooo... Are you saying that the "superclocked" cards are better, or not? I'm confused...

Those "superclocked" cards are just factory OCs. If the non superclock version is cheaper, go for that. You should be able to hit the same speeds. Comparing an E6400 to an E6600 is more like comparing an 8800GTS 320mb vs the 640mb.
