GTX 660 problem

Hello all,

i've bought a gtx 660 from MSI in october 2012 and since last week it suddenly works bad.
i have a super bad fps rate and for exampel i can't play mw3 no more because the graphics suddenly suck real hard...
you can see the pixels at high and low image quality.
i went back to the store with it today and they said it's not the Graphic card but some setting in my system or something like that.

could someone please help me?

Thanks in advance

    Could be a problem with your power supply. Do you know what it is?

    Do you have the option to purchase a new one or borrow one from someone else?

    And out of curiosity, what did the people at the store do that made them come to the conclusion that its not the card ?
  4. The motherboard requires an 8-pin suppot power connector to which the PSU does not provide (as best as I can tell) so perhaps you are not using the 8-pin connection but only a 4-pin connector and forgoing the other extra power surplus. Doing so will impact on all components including the ram.

    The Video card does require a 6-pin power connector to which the PSU does provide.

    It's not the video card at fault but I'd say that the 8-pin coonector the the motherboard is not being fully utilized.

    It shouldnt even work at all without supplemental CPU power.
