are there any tweaking programs for radeons that will work under vista 64 bit?

i want to try running without CCC but know that there is problems because of driver signing with vista.

not sure about rivatuner's support with ati cards for anything but overclocking/fan control/monitoring, but it works fine in vista x64 as it comes with a signed driver patch thingy in its rar file, you can get it from guru3d.com if you wanted to test it out.

ATI tool 2.7 beta3 works under Vista64.
