Clevo p150hm Compatibility (AMD\Nvidia)

i have a Clevo p150hm (Sager NP8150) that came with an HD6990m ati card, but the card got fried...

my Question is : will an Nvidia card work in my laptop (as it originally had an ATI)?

*i know that it should be a Clevo branded Nvidia gtx460 - gtx680


thanks
