Ok that's a pretty standard windows setup. Well make sure your priority is high, you can try -f1 I believe the flag is for GUIMiner for your secondary card, and maybe -f30 for your primary card (you can adjust this if things get laggy). If that doesn't work you can try opening up a second client on the same card and see if that changes anything just as a diagnostic test.

Download MSI Afterburner. While mining, check to see if your gpu core is fluctuating. If it is, open up catalyst control center and change your power settings to +20%. If it's already at +20%, change it to 19%. For my 6950, every time I change my core speed, I need to change my power settings for my gpu core to stay steady. If I don't, the speed will vary rapidly between 780 and 1000 mhz.
