I published a guide about the NVIDIA driver installation process yesterday which looked at all the optional modules that get installed with the express installation option. Most of these features may not be needed but are installed by the majority of users anyway which may mean additional startup items and processes running in the background. I promised to do the same for the ATI Catalyst installation.
I do not own an ATI card right now which makes it a bit difficult as I can't test the effect of not installing components on the system. What I can do however is explain what each component is for so that you can customize the installation and avoid installing components that may add startup items and processes to the system despite the fact that you may not make use of their features at all.
Hope that helps AMD / ATI users who have troubles making decisions what to install during driver installation. If you have any questions or corrections fire away.
