Does my 24" iMac have Descrete Graphics?

[Yerman]

How can I tell?

24" 3.06
NVIDIA GeForce 8800 GS
Late 2008 I think?

Thanks for your help...

BTW, the reason I am asking is because I am interested in this new Steam software that Valve is putting out and I want to know how well my Mac will do with the games. Thanks.
