Unless the price discrepancy between the Duron and the XP becomes fairly large, I don't think I'd gamble buying a Duron in hopes of enabling the extra L2 to make it an XP. The Duron is going to be a low demand part, so there is going to be a low supply. Chances are that AMD will not make too many Durons from chips that could be XPs.

Not very useful, but interesting.
Unfortunately, I believe my Duron 900 is too old to have the extra cache on the core.
Not the old Spitfire and Morgan models.
