Odd, I swear when I was using cgminer 2.4.1 it said the intensity limit was 10.
Right now I'm using the 11.12 drivers, which I believe are the oldest drivers with 7970 support, so I'm not sure what to say. One GPU going, perfectly fine. Many GPU's running, GPU usage is between 90-95%, so I'm missing out on a good bit of performance between all the GPU's.
Ignoring the gpu usage reported, what hashrates are you getting? Max you should get about .6MH per Mhz of engine clock speed.Right now I'm using the 11.12 drivers, which I believe are the oldest drivers with 7970 support, so I'm not sure what to say.
