yes i agree........i think i got like 3.0 ghz on my Q6600 with stock......now im running like 3.65ghz on my Q6600 with an OCZ vendetta 2. I can run 3.8 ghz but i dont like the voltages or the temps much. I can run 3.7ghz and a bit more on 24/7 but theres no point, not much of a performance boost going past 3.65ghz unless u get to like 3.8/9 or 4.0
It is fun though, but you need to be careful about what your doing.
