Overclocking in Vista?

I've been searching through the threads and I have found very limited information on the ability to overclock with Vista. I have read around and some mention that Ntune and ATItool may work, but I didn't see much in the way of first-hand experience using either in Vista. Can anyone confirm that he/she has been able to overclock in Vista using Ntune, ATItool, or even coolbits? I'm looking to get Vista soon (Sadly, I will be forced to for DX10 ) and just wanted something concrete that OCing is in fact possible in Vista. Thanks!

Install RivaTuner 2.01
