OK, it would appear that some believe that they have a 3400+ 939 pin processor. If you get the chance, would you please run the CPUZ program (can be found at CPUID website) and see how your cpu is identified, what core, what process (.90 or 1.30) and what the highest mutiplier is? I saw the 3400+ at Newegg about 4-6 months ago, but it quickly disappeared. If you got this cpu from Newegg, I'd be curious to know what they sent you.
