I have the nvidia 980a/780a chipset with onboard video and 2 9800 gt's
SHould I run the physx on the 9800s that are sli'd ? or pick the 980a chipset gpu to do Physx. it seems the areas load a tiny bit faster when the 9800s are doing the physx stuff and not the MB/980a chipset...
is it worth getting a 3rd 9800GT to run the physx stuff or pointless?
