Ok, we'll if it isn't going to do much of anything I won't bother. I figured if the 480 was handling straight physx it would take alot off the other two to perform the other graphical duties. My understanding is the 480 is still near the top on most charts, albeit power hungry and hot running. But I really don't know much about how it all works.
On a side note, is it better to set the physx in the control panel to use one of the gpu's or set to CPU? I have a 3770k for CPU.
Thanks for the replies. This place is awesome as usual.
