More about option
  1. You probably be using old gpu drivers. Update those.
    for example, try 285.62 nvidia driver.

  2. You are using a 448 core with a 384 core, that is why.
  3. Yes, :), only you can sell one the 448/normal one and get the proper ones, or get the 560 ti one as the PhysX dedicated processor :).
  4. PSU is garbage, I doubt you want to SLI cards on that POS anyhow.

    ok so... I bought the wrong card :( unlucky
    I just receive 2 days ago. should I send back?
    My current nvidia driver version 295.51

    Nvidia control panel/ PhysX configuration use my 2nd card (MSI GTX 560 ti Twin Frozr 2 oc edition 1GB DDR5 )as a PhysX processor.
    Can I leave like this option or buy a new card?
    And also how can I get the 560 ti one as the PhysX dedicated processor?
  6. You can swap out cards to make your preference PhysX configuration. You will get high performance of PhysX but not an SLI, the performance of gaming only be like around a 560 ti 448 (May be better), only PhysX would be very good if you do this setup (you won't get SLI performance). You better sell and buy a proper card :).
  7. Yes, the 560-448 is a a 570 (G110) card with a disabled SM unit while the 560 Ti is a G114 based card.....they are not compatible for SLI.
  8. ok
    Thank you so much all for help me. I will get a new card. :D
  9. I would highly suggest you get a qaulity PSU as well. PSU dying suddenly has the chance of taking out your entire system.
