Possibly. Like I said, once I limited the gpu's 2xfermi and 2xg80 to all use only one cpu core, the fermi's PPD both suffered, can't remember exactly but I think it cost them 750-1K ppd each. That was enough for me to give up on running smp on that rig. You will probably want to experiment running the smp on 4 or 5 cores and see how much of a difference it makes. I'm sure an x6 will fare much better then my lowly dual/tri core.
Do let us all know what you decide and how it works out!
