Quoting treborblue, reply 120I'm not really into overclocking, does it make all that much difference?
I really don't think so. Many people talk about overclocking their CPUs, but when I watch the monitor for mine, I see the clock speed changing constantly. I don't know what causes this, but the temperature is not the reason, as it is staying below 30 Deg. C.
Intel cpus use a technology that allow the processor speed to dynamically adapt to the workload, that is likely why you see it move around. This is designed as a power saving feature.
Overclocking Can and will provide a significant performance boost none the less. It will raise the max speed. It does depend on the processor used though, some are bad overclockers, some are good. I had a 30% speed boost on my last machine due to overclocking.
