I have a Foxconn FlamingBlade GTI mobo that supports crossfire but not SLI.
My main graphics card is a GTX470 & since I have a spare PCIE-16 slot I thought to throw in my 9800GT.

The question is will I just add it, & give it power from the PSU, remove the old driver & reinstall a new driver so that it detects both of the cards?? or how

Besides, is it worth doing so??? will I see performance gains in games that have physx?

A step by step guide is highly appreciated

I don't think your mobo has to support SLI in order for you to have two gpu-s, one for graphics and the other for PhysX.
Just install the card and reinstall the drivers and PhysX software. It should work.

I think you need a SLI support but there are a lot of great Mobos out there that support it.

you don't need SLI for PhysX. I have done it before on a crossfire board.

It can be done technically speaking on a non SLI mobo

So I just add the 9800GT
Boot the system & install the NVIDIA-PhysX System Software

"thats what im a little fuzy about"
Do I just install the PhysX System Software as a driver or do I have to install the whole Nvidia driver?

Whichever works.
