a duron 600 is like $45, with $10 on top of that for shipping. You can probably get $25 for that though, since its not high end, and well most people who have a bx for upgrading to that even at 450 wouldn't need it since everyone who would be upgrading a bx has at least a p2-350 anyways. Its probably good for servers and such, maybe someone who gets a free lx might want it
