SoLoR do not know if previous 6590 or original 6685 had the same problem:
When moving scroll bar of Firefox i see the CPU Usage to increase for firefox.exe.
That is ok, have seen it also on my laptop,
but i can see also some crackling noise coming from a game
that is running in background (alt+tab in firefox while playing and
immediately start scrolling).

Can you confirm this behaviour? I would try with Media player for example
and see if there occurs too, but i am at work again (all thoughts come up here )
