im gonna pretty much guarentee that the -5b G's, the best of em, go to ballistix, and the best of those go to the pc4000, and the best of the pc4000 goes to the tracer, but still, if they have the potential to hit pc4000, then they are gonna be pretty decent chips. but warning, they are REALLY hot, like hotter then any chips ive seen. they need airflow on em.
