O.C. of Nook, what exactly gets O.C.ed?

Having had some experience with O.C. of desktops, I'm aware that when you OC the CPU, depending on hardware architecture, this may also mean OC of other parts such as memory, GPU, ect...

Anyone know if the GPU and DSP are also overclocked? Haven't tried it on Froyo 0.6.6, but would be excited if the GPU and DSP where also getting a little help.

Youtube lower resolution stuff looks pretty good. Higher resolutions suffers a bit.
