Apple Benchmarking ???

Hello everyone. I am new to the forum and a somewhat new apple owner. I will probably be posting within this category quite often as I am interested in media producttion. I run a BMW enthusiast group and do short films about our group. I am excited to be able to use my new machine to compile many of my two year old footage into some interesting and exciting short films.
Anyways, I just picked up a quite nice Powerbook and would like to run a benchmark application to test the system hardware capability. Specifically the video card. I know 3DMark (madonion.com) runs a very nice application for PC, but unfortunately there is just not enough software out there for macintosh.
Any help would be greatly appreciated!
