I may have found a fix for the cpu usage issues when using Fermi cards on some WUs.

I don't have Fermi so I can't try it...but the OP of that thread reported much better results on bigadv.
Assuming that your GPUs are on the i7, you should try removing the affinity lock from both in the advanced options of -config and set the environment variable NV_FAH_CPU_AFFINITY to 255. This will spread the gpu load across all cores and avoid imbalancing the SMP threads. You might pick up a little speed.
