I'm using GUIminer scrypt to mine with CGminer and I just got a 7950. On 5000 series cards GPU usage was always steady while mining but my 7950 jumps up and down all the time. Any idea what could be causing this? The big drop is me stopping mining for a few seconds. It jumps from around 64% up to 99% and back.

I used to have really bad fluctuation with all four of my 7950's and I noticed it went away after I closed GPU-Z and all of my other monitoring software. I don't know if it is a related issue to what you are having but maybe this will help.
My 4x7870 LE do that if I have the intensity set at 13, but not 20. Minimizing GPU-Z and Afterburner solve the issue for me as well.
