So even though some people claim they are based on the same chip, gts250 is a quite bit of improvement over 8800 series. You wouldn't wanna spend money on a 8800 for PhysX right know unless there is one laying around.
I'm pretty sure the increase in Vantage came from the extra stream processors on the GTS250 as it has 128 of them where the 8800GS has 96. The 8800GS I had was run at 750/1800/2000. It was a little overclocking demon for sure. In any case, I'm happy to confirm my findings with a review that mirrors my results. The bottom line is that you just don't need a very powerful card if it's just going to be a dedicated PhysX card
