Oh, here is how you do the coolbits thing. Add the following text to a notepad document...
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak]
"CoolBits"=dword:ffffffff
"NvCplEnableRotatePage"=dword:00000001
"NvCplEnableAGPSettingsPage"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\nv\Device0]
"NvCplEnableHardwarePage"=hex:01,00,00,00
"NvCplCpqConfiguration"=hex:01,00,00,00
"NvCplEnablenForcePage"=hex:01,00,00,00
Now save it as coolbits.reg. Double click it and add it to your registry. Restart your computer, go to properties>settings>advanced, then click on the 7600gt tab, and now you can look at all your new options. OR you could just download rivatuner and use that.
