God man, the 3400 are great processors. If you have a Clawhammer, then your insane. But either way, the 3400 will still do great. This type of processor is one of the high-end Athlon 64's, so it will do just fine. But you really are just wasting money.
But like i said, the 3400 is a high-end Athlon, its alot more flexible then the 3200/3000 Athlons.
