Most CPUs last a really
long time unless horribly abused.

It's nearly a given that the more expensive, unlocked, QX9650 is going to be in more expensive systems with faster GPUs and/or be more heavily OCed.
On an silicon level, there is probably just as much variation between two random QX9650 samples as there are between a random Q9550 and QX9650, assuming both are C1s (there are no C1 Q9650s and no E1 QX9650s so I'm comparing the the Q9550 and QX9650, both of which exist in the C1 stepping, for the sake of argument).
