Do you see the "ripple" effect when you drag out a new Dashboard widget?
That appears to be the simplest test you can perform.
I don't see anything about multiple levels of Core Image support
here. Quartz Extreme is a simpler technology that lets the GPU do
window compositing (i.e. window shadows and translucency are done on
the video card).

System Profiler says that my machine DOES support CoreImage. I
guess there are different levels of support for CoreImage.
Also the list does not include the new iMac, which I find hard to
believe since the graphics system is DirectX9 capable with 128MB of
RAM.
