Overclocking the Radeon 9600 Pro: What's more important?

[Embryo]

When overclocking the Radeon 9600 Pro, what will make the difference? Rise the core speed or the memory one? Currently I've been able to keep my card stable at 492.75/344.25.

What's faster? To rise the core or the memory clocks?

I`d say the core on the 9600, as it has half the pipelines of a 9500. But raise both as high as they will go.
