Q9300 vs Q6600: which is the better overclocker?

[whiplash000]

I own a ASUS P5N-D, and the new CPU will be replacing my old Intel e2140. I'm no stranger to overclocking, so I'm looking for the best overclocker.

Will my stock e2140 cooler preform exactly the same as the stock coolers of the other CPUs?

Also, what's the lowest price from a reliable seller you guys know about? I found both for around $130 on ebay, so I'll proabally order from there.

Outside of the used market, I don't know where to find a Q6600 anymore, so no reliable source there.
Most of the stock heatsinks from Intel perform the same as they're the same heatsink, though designs do vary over time so I can't say for sure the heat sink you have now is the same as what ships with a Q9300. However I would highly recommend you get an aftermarket heatsink for overclocking a quad core processor, it is going to run much hotter than the e2140 when at the same clock speed.
I believe the Q6600 overclocks better, it is an excellent overclocker because of the lower fsb and higher multiplier compared to most of the newer Q8XXX and Q9XXX products.

Well, I bought a used q6600. Hopefully it'll work fine...

not exactly true... I had Q6600 which went to 3.6 GHz on air... But I switched it for Q9650 which is now running @4.2 GHz again on air with the same cooler (IFX-14).

The Q6600 is excellent overclocker but the problem is that it is very hot and power hungry. The Q9650 is 45nm and has better heat/power characteristic, hence better overclock.

This is correct. In most instances, the 9300 will be the better overclocker.
