I got a MBP with the 9600 dedicated graphics and it provided no discernible performance improvement, it blasted the fans and it made it a very hot laptop. When I bought a new MBP a few months later it was a no brainer for me to get the cheaper one with the integrated graphics as that was the setting I ended up using most on the original one anyway.
I think there are very few use cases where the dedicated is required. They certainly exist bit they are a small minority. The 9400 is very capable.
