1. Order the Q6600.
2. Install it.
3. Use CPU-Z to determine if it is B3 or G0 stepping
Lol then if its B3 you just want him to ring up newegg and say na take it back?
My first port would be to ask newegg and see if they actually have any, i would think they would know. If they do say that they have them then say you want one and order as such... then there is a paper trail if you dont get one. Other than that i would say luck of the draw.
