UGH....

been trying to figure this out all day with no luck...
GPU load 80-85% 2x 6950 non crossfire and physically connected to two monitors.

I ran the bench for moo and of course core 3 on the I7 2600k is showing the best to use... So i went to the project website and made a new profile home and set the -1 cpu deal to 3, but is this corect since it has hyperthreading should i have used 6 or 7? Its set to 3 ATM. I updated the project and it set the machine to home but no dif still saw dips in the gpu usage 80-85% every sec while running 5 cpu WU aswell. So i dropped to 4 CPU WU and saw some improvements GPU load was 85-94% but still dipping. So from reading other threads i installed lasso64 of course this is a little over my head... So what i did was told everything running to use 0-5 and set D***stream.exe and D****ati14.exe to use CPU 6 and 7 this was a huge leap forward hitting 94% without a single drop just steady as she goes so i thought i was done and good to go only to find out once it finishes a GPU WU it changes to using 0-5 Affinity on the new GPU WU... Ugh what did i do wrong???
