Athlon XP or MP?

ok why does the 2400 MP cost more than the 2400 XP? Are the MP better? I always thought XP were better. Whats the dif?

the only thing different is the fact MP chips are tested for SMP operations and the last L5 bridge is connected. Thats about it. CHeaper to go with an XP and Mod the L5. but if your using it a single CPU machine theres no need to do the mod.
