    I have 2 560Ti in SLI.
    The question
    In nVidia control panel there is an option to set PhyX to
    Automatic
    GPU1
    GPU2
    CPU.
    Which is the correct/best option and why

    if you want it GPU specific you select GPU 1 or GPU 2, which is hardware Physx layer.

    Automatic will select and detect the best option for your setup in most cases-

    Software Physx is used by the CPU, thus really not optimized for that.

    Honestly Id leave it in automatic since you have 2 of the same cards in Synchronous SLI config. reading from another forum physx will be utilized on both GPUs in automatic, and it wont disable SLI effectivness.

    personally i always found the best performance for any physics intense game just to set it to GPU 2 (non display adapter)

    Thank you guys
    nVidia says to set PhyX to 2nd GPU. I think it would be safer to leave at auto.

    Since You have 2 Homogeneous Cards Auto Would be best (splits Physx Load between both cards reducing frame rate hit)

    if you had 2 Heterogeneous cards, (1 is weaker than the other) it would be best to set Physx to the weaker card.
