Poll, what batch would you buy?

That is flat out wasting money for no reason.
Just get a better cpu cooler like a xigmateck dark night,thermalrigtht true, or noctua.

Use OCZ FREEZE or IC Diamond thermal paste to make temps drop

just get a better cooler mate

Agreed

Are you going to be exchanging it or buying a new one?

I might be lucky enought to exchange it

Well if you don't like the chip and you can exchange it then definitely do it, but if you can't exchange it then don't waste all that money for a few hundred MHz.

Load temps on a stock cooler mean nothing really, you need proper cooling to see how it'll OC. Put the phase on it and see what it'll do. Even if you do exchange it you very well may get a worse chip, and you don't even have a baseline of comparison from your current chip to know if the new one is good or not.
