the only thing they'd be predominately faster in is copying over files to some degree since it has bigger bandwidth, but it's still going to be limited by readspead which is because they are 7200RPM and all.
I don't think you'd really notice any difference though, even with 10Krpm drives gaming isn't faster because gaming doesn't use the HD besides to load up levels (which is faster) and the game itself, but as far as actual play goes it's dependant on your CPU, RAM, and GPU
