Using Riva tuner hardware monitoring I noticed that with only desktop showing my gtx 280 downclocked correctly to its power saving 2d mode, but when I started surfing it changed to 3d mode using far more power. I started to disable add-ons in Firefox until I found out which one was causing the 3d clocks to trip and it was a program called Piclens or Cooliris that was causing this issue.With no Piclens installed I can now surf the web in low power 2d mode.
