    i have my old 8400gs and my new 9800gtx+ if i put my 8400gs in my second slot doing physics will i have to run at 8x 8x in stead of 16x ?????? as my mother board only suports x8 x8 and not 16x 16x

    so would it be worth it or not???

    Yes u'll have to set the mobo PCI-EX second slot to 8x as well with both slots running at 8x speed.
    BTW its not worth using 8500/8400 as physx cards.They are way too poor for the job.
    Guys i posted a PhysX performance comparison just to help u guys.Take a look at it.

    And where would this wondrous thread be? I searched this forum for threads started by you, but only found your Vid Card comparison.

    I would just run your 9800+ at 16x and forget about using any of those cards for physX if it's going to cause your main card to run at 8x. Doesnt seem worth it imo.
