Applications are pretty varied, but media encoding applications would be the ones that would likely see the best increases as they are very CPU power dependant (and dual core would be even better than just an overclocked single-core). Other applications such as email, http, and Office likely wouldn't be affected much (i.e. how much faster does a browser window really need to open?). As to exactly how much faster that divx movie would encode for you on an overclocked chip vs a non-overclocked chip... my question would be, how much of a difference would you *want* to notice? If it went from 3 hours down to 2.5 hours, would you care?
Running games faster/better is more directly related to video power rather than CPU power. However, this varies depending on resolution and settings. The mainstay in the past has been to benchmark games at 1024x768 with no graphical eye-candy in order to accentuate the power of one CPU vs another. Recent games have shown that, even at lower resolutions, CPU power (even dual core) doesn't affect performance much. At higher resolutions such as 1600x1200 and above with AA/AF, CPU speed/power plays almost no role in most cases.
Oblivion at 800x600
FEAR at 1024x768
COD2 at 1024x768
Obviously, there are no hard-and-fast rules and there are exceptions.
Hexus recently showed Conroe whooping AM2 by 40% in Far Cry at 1024x768... but that gain drops to essentially 0% at 1600x1200 with AA/AF in Quake4.
So, depending on what resolution you play your games at (and what games you're playing), you likely won't see too much of a performance increase from overclocking your CPU. But it is nice to buy a 3000+ for $100 and overclock it to FX-57 speeds for free. It's certainly a much better deal than actually buying the FX-57 itself.
