And are you 100% certain that your errors in "every" games you play are caused directly by the GPU drivers ? You know ... when there is errors in games, it can be caused by SO many variants that pointing at GPU drivers right away might be a little premature. Is your OS stable in the first place ? Do you over-clock ? If so, did you verify your OC'ed hardware's stability with precision and came to definitive conclusions ? If no OCs are concerned, then are you using the lastest BIOS version ? Is your CPU model compatible with the BIOS version you're using ? Do you have the latest Chipset/Mobo drivers ? Sound drivers ? Latest DX version installed ? Etc ... etc ... etc.
As for CCC, do yourself a favor and just don't use it, errors in games or not, there is no reasons to use it over ATi Tray Tools in the first place.
