GeForce triple-digit line-up is the predecessor to the quadruple-digit GeForce line-up.
In your case, GeForce 320M > GeForce 8000 series.
Though, stepping into the realm of mobile chips, I don't know, but the GeForce 8 series is pretty old (only worth $20 now, which is practically free compared to $300 GeForce 470) so you're probably okay...
EDIT: It's a MBP? You'll be fine. My friend plays TF2 on his MBP.
