Hey guys i got a quick question. When im running BF3 and i have Afterburner up showing my usage and core clock speeds, by the way i have 2 gtx 670's, it shows gpu 1 going slightly higher. Example: GPU 1= 1220.....GPU 2= 1160, does anyone know if this is normal and does anyone else have the same thing happen to them? I ve tried messing with nvidia control panel as i thought that having my physx setting on gpu 2 made it slower but i tried switching between the 2 and it didn't make a difference, at least it didnt show in afterburner. Any answers would be appreciated and im hoping this is just normal because its by a small amount, but you would think the exact same gpu's would be running the same core clock speed. thanks.
