What is the latest operating system i can run on a 466 MHZ G4?

Mac OS X 10.5 as noted here.

(55933)

Leopard (10.5) may run on it, but it may not run well if the graphics card does not support quartz extreme, since Leopard is a very graphic intensive operating system, compared to the previous release, which is Tiger (10.4). Can you please go to About This Mac in the Apple menu, click on more info, then click on graphics or AGP? It depends on which version os OS X is installed. Can you please post the graphics card model that is in your computer? This way we can see if it will be able to run acceptably or not.
