Here is link to Nvidia explanation about 10 bit support: http://nvidia.custhelp.com/app/answers/detail/a_id/3011/~/10-bit-per-color-support-on-nvidia-geforce-gpus
So basically what you need to know, GeForce is supporting 10bit depth only in full screen DirectX applications. But games are not supporting 10bit depth. You can make use of 10bit only in professional applications in which 10bpc is not supported by GeForce. So conclusion is - there is no point on having 10bpc on for any other usage than professional applications with Quadro card.
