oc ur pc dude and you will get lot of stuff for you table showoff if not done properly....at least your proccy can be used as kwel and hot paperweight....lol.
OC & Modding Overclocking - Disadvantages?

two reasons:
First, a processor is designed to run at its rated clock speed for its entire expected lifetime, even in worst-case temperature and voltage conditions. As a result, a brand-new processor has frequency headroom at nominal voltage and temperature.
Second, the speed distribution in the fabrication often doesn't match the price. To meet demand in this situation, Intel/AMD takes fast parts and sells them as a slower speed grade.
In other words, a particular die design is used to fabricate the processors which are packaged to run at different clock speeds, as it might become too expensive to have different fabrication processes for each of the processor models you sell. Such a part can easily be overclocked, as it is designed to run faster than its label indicates.
The only real use of overclocking is that one gets some free performance out of a chip, for which otherwise you would have had to pay extra by getting a higher clocked processor. (of course another thing that one gets is the bragging right of running something faster than it is supposed to run
). on the other hand, to get the extra performance u might have to give some extra voltage to the processor(food for the extra work it does
), and if overdone, it produces too much heat and the chip just dies, or burns, as u saw in the video the safe temperature and voltage limit depends on the chip. for core 2 duo, intel recommends to stay below 1.36v, but people have gone above 1.5 but ONLY with good cooling.
the processor that you mentioned is said to go upto 3.8 ghz on stock voltage, using a good cooler and giving a bit more volt one should cross 4.0 ghz.
i'll say you should reach at least 3.5 ghz, approx 16 % performance gain.
about life loss, if you stay within the temperature and voltage limits, the loss doesnt matter much

Thanks very much, tirthankar. This helps!!
Every electronic component has an rated lifetime which is determined by tests conducted on it.It can be anything like 10yrs@5V and its not a proportional measurement.If u supply more than that then it "might" be 5years@7V.But I am assuming that you won't use it that long.
Second thing is the temperature.It has a killing effect too.So the combination can drastically reduce the life time.
That's the catch.

Moderate overclocking doesn't do much harm to any computer chip.Many GPU's and CPU's are under clocked to differentiate from their higher spec'd siblings.
