30 days?!?! That would certainly be a major rip off for the price difference. Unless you OC and lose the warranty anyway. According to TigerDirect's site, there is nowhere near that big of a difference in the length of warranty between OEM processors and retail processors. Some are the same, depends on the processor. The lowest I found on the site was 36 months for a retail CPU compared to 12 months for OEM.
