Since a few weeks ago, ATI users live in a happier, more free world.

Some GPUs have the equivalent of speedstep. fan-noise stays constant
here with windows stuff going on. Makes some noise only when playing
GPU hungry games.

Agreed, making it a requirement is stupid... I _chose_ to do it
because I find it fun, and because it has no impact on my system.
