Nvidia physx driver ?

[m4r1n7]

OK guys can you install nvidia physx driver after you already installed only graphic driver and audio driver from the nvidia site?
Can you download that physx driver from their site manually and is it the same for every nvidia card? (I mean I dont need to search specially for mine gtx 970 card physx driver)
So I want to install physx driver now for my card without uninstalling rest of my drivers

and is that driver necessery for gaming?

Yes, you can just install your graphics driver package again, but this time choose "Custom Installation" and then check off only the PhysX drivers from the list. If it doesn't allow you to only install PhysX, there's no harm in installing the main graphics driver again on top of your current one.

Last option is to install the standalone PhysX drivers.

Yes, you do need them installed for most gaming. Some games use the GPU to accelerate PhysX, others use the CPU, some don't use PhysX at all. In general, its hard to tell which games support which type, so just having the PhysX driver installed either way is the best way to go.
