GPU-Z is the perfect companion to CPU-Z since the latter can`t give information about your video card, with GPU-Z you will know everything there is to know about your video card like its name, default clocks, display information, driver name, Etc.
in addition you can upload your results to an online database showing all the results uploaded so far, unfortunately i couldn`t run the program because of the crappy savage integrated card that i have in my computer, but don`t let that let you down since the program supports most mainstream cards from ATI and Nvidia plus since its being constantly updated you can be sure it will support future cards too.
GPU-Z is a great little utility for windows 2000/XP/Vista.
