Which One Is Better?

[RejZoR]

Buy some lower end Core 2 Duo CPU and a decent motherboard with overclocking capability. If you don't overclock C2D you're wasting like at least 40% of CPU's actual value.

If you overclock you're wasting the guarantee but it's your decision

Why would you tell them you OCed the cpu, there is no way they could know that unless you "burned" the cpu of course ...

overclocking is the cause cpu damage/ shortend the life spand of the processor

That's if you over do it with the voltage(why would you do that anyway), with these new intel babies you can get quite good overclocks even without raising the voltage(eg. my e6420 goes up to 2.9ghz on default voltage).
