If you've ever fried an expensive CPU trying to overclock the thing, you should check this out. Intel is introducing something called the Performance Tuning Plan, which in plain English means overclocking insurance.
Yes, for $20-$35 your Core i-whatever processor can be covered against you screwing up an overclock, with a one-time condition that your CPU can be replaced entirely. Brand new.
The PTP is currently in a pilot phase at the moment, available for a six month span. As PC Gamer notes, though, serious overclockers are more likely to crap out something on the motherboard rather than the CPU itself.
