I have the *EXACT* same stepping as that one - I got it to 2.4 GHz on decent quality air cooling (SLK-800, 50 cfm fan) with some voltage (1.825 Vcore) with ease, and it is currently rock stable at 2500 MHz with a nice 1.9 Vcore - not bad, but not *really* great either. I am a temperature worrier, and thats the only thing that stopepd me from running it at 2500 MHz on air. I am currently held back by RAM, and being limited to a 12.5 multiplier. I suspect that this chip will step up to around 2600 MHz with a Vcore at around 2.0.
With good RAM - allowing for a nice FSB overclock - I hope that my chip still has a lot of potential left in it now that I have managable temperatures.
I guess that that is a good enough deal to bid on, but I suspect that the price will go up to more than the chip is really worth.
