you won't see much difference between this and the 3200+
the Athlon's are rated by their performance and not their clock speeds; the 2500+ is 1.67GHZ but performs as well as a 2.5GHZ Pentium 4
the reason being is that the Athlon's can complete more instructions per clock cycle than the P4 can, in the case of the 2500+ and 2.5GHZ, the Athlon XP would perform 150% as well as the Pentium 4 if they were to run at the same clock speeds
