MacBook Pro :: Is 9600 Has Same Speed As 9400

I have a late 2008 MBP with the two graphic cards. Something I noticed was that there was almost no noticeable between the two, even during tasks that would benefit from the 9600, like gaming. For example, to play the Mac Bioshock demo with no lag on max graphic settings, I had to lower the resolution to 1024 by 640 on the 9600. When I tried those same settings on the 9400, it was almost exactly the same performance.

Some I did notice was the under the 9600 stacks appeared much smoother, but scrolling up and down in any window (browser, finder, ect.) was extremely jerky. Under the 9400 scrolling is entirely smooth.
