I see this topic argued time and time again in multiple threads, so when I recently did a fresh install I decided to attempt to end the speculation on how much memory it actually does use. The method was simple, installed Xp Pro then patched with SP2 and took a screenie. Installed Catalyst 6.2, .net, CCC with a screenie after each, then finally took another with CCC open. The results:
XP Pro w/SP2 fresh install
after installing 6.2 drivers
after .net 1.1 install
after CCC install
with CCC open
From these shots it looks like a full install of ATI's drivers, .net and CCC use an extra 80MB of memory, going by commit charge. While not slim by any means, it's hardly the 300+MB that some people have been claiming. I'm not a fan of the CCC myself, but until ATT fully supports the x1900 series that's what I choose to use.
