I for one hated gambling on overclocks that could brick my expensive hardware. I’m glad the equipment being sold today comes at max performance out of the box and that the reputable company making it will support it.
Whether you're comfortable going down this unsupported/warranty-breaking route is another story, but it's certainly not the case that all processors nowadays are sold at their peak possible performance out of the box.
