Creating a new Application Profile?

I have a Dell Inspiron with a GeForce 6800 Go card. When I got to
Display Properties-->Geforce 6800 Go--> Performance and Quality
Settings, I can see a default drop-down list of games, and buttons to
"Modify Profile" and "Remove" (profile). There's no new button.

I did try modifying a profile, then trying Save As, but the end result
was a mixed up profile.

Anyone know I'm meant to create a new one?

P.
