I disagree, the Extra multiplier doesn't make it "easier" at all since getting a higher FSB is easier with a lower multiplier. What it does is give you extra mhz in the multiplier at the same FSB as the E6300. The thing is though, the real power comes from the FSB and the extra multiplier doesn't add much performance.
They are the same overclocking in terms of FSB but the E6400 x8 multiplier just makes your CPU look more powerful becuase it will be clocked higher but in terms of even benchmarks theres not much difference. I just don't see the point in really wasting 40 bucks that way.
