If the benefits are negligible, why do people spend more ( sometimes lots ) for a 100mhz speed bump ?
All Intel is doing when they bin their chips, is overclocking them and charging you for it..
Intel counts on this for millions in sales..
An overclocker can get a 1,000 mhz bump ( hardly negligible ) for free, and no risk of damaging the CPU ..
By the way, what CPU do you have ?
