ThunderBird serial numbers

[TELeast]

I am planning on getting a new ThunderBird (750-850). Does anyone out there who knows what serial numbers/week numbers I should be looking out for.

All I know at the moment is that the Blue core is better than the green core.

This is how I bought my Celeron 300A s. I bought 7 of them from the same tray when I found out that the serial/week numbers were of the good batch. They all overclocked to 600Mhz.
