How can you see if a graphic cards supports Transform Lighting

I am no computer-genius but I can tell you a website from where you can find about almost everything you want to know about your computer's gaming capacity.

www.systemrequirementslab.com

Go to this site and select any latest game (CoD4, World in Conflict, Crysis etc.)
Click on 'Can I run it?'

You will get your answer when you get the detailed graphical capability of your PC.
