Here for all you doubters and haters out there. I think these tests speak better than I do. I know what you will be saying, but you can overclock the q6600 to 3Ghz, well yeah but then you can get the 8400 at 3.6 and so on until the quad tops out and the e8400 will keep on going. I HOPE THIS WILL SHUT YOU UP FOR GOOD!
"I've never had a Dual-Core overclock so high and still remain stable, so I was skeptical. I put the CPU through all it's paces... and nothing could stop it. As you can see in the screenshot below, it ran a collection of benchmarks without issue. The important thing to note here is that this is a true overclock that increases performance. All results scale well, so heat didn't become an issue at all, despite the chip running at an average of 68°C on each core."
"If you take a look at the Sandra results, you will notice something interesting. Our E8400 at 4.2GHz effectively passed by the Q6600 in terms of raw performance. Despite having half the cores of the Q6600, the huge overclock made up for the loss... and then some.
Another thing that strikes me is the Super Pi result. While not that relevant today, when Conroe was first launched, it was deemed extraordinary when enthusiast overclockers broke through the 10s mark with the new processors. Now, even us casual overclockers have the possibility to break through that milestone... on air. That is beyond impressive.
One downside here is that I believe this CPU still had more room to push. I became limited by the motherboards FSB, which may or may not have had anything to do with the CPU. Running 470FSB was fine, but moving up to even 475FSB would spawn errors in SP2004 within five minutes. While 4.2GHz is undeniably impressive, I can't help but feel it could be pushed a bit higher."

"Case in point: In summer 2006, the E6600 sold for $316 in quantities of 1,000, which would end up being $350 once sold by the e-tailer. Fast forward to now, and we are seeing a far superior product in terms of overall efficiency and speed, and it costs 40% less. Of course, such is the natural progression of things, but it's certainly a better time than ever to PaPP (ponder a processor purchase!)."
Now you can all go techgage.com, here is the link:
http://techgage.com/article/intel_core_2_duo_e8400_30ghz_-_wolfdale_arrives/1 and bash the guy who wrote that article and tell him, while swearing on your quadcores, that the e8400 is a far worse chip than the q6600. As for me I hope this will end this debate that has become pointless, because of trolls that talk out their arses and don't back up any argument and generally just flame people that are trying to help someone...
EDIT: Ok fixed it.
WOW! Now that's a really big difference! 
I bet it can't be ever done! Too bad it has. Just let it go Dom...
So do you think the OP will/could run his rig with an E8400 at 5.7Gig, probably on LN2 with a heavily phase cooled and voltmodded motherboard?
