I would note that at my friends how the something simulate happened today.
he has a 6950 and at high his gpu is at %95+ but when i put it on medium for better performance it only goes to %70... could this help figure the problem out?
You're most likely CPU bound. The graphics card is waiting for the CPU to send the frames to it so it can render and show it. Usually its the other way around.
You have headroom on the graphics card so either overclock the CPU to help it keep up or put a bigger load on the graphics card to try and balance it out.
When all is balanced, your GPU should be the one struggling to keep up in games (99% load fluttering).
