I have an opportunity to buy this card extremely cheap. I'm thinking of adding it to my system as a dedicated PhysX card. I have two questions:

1. Will my PSU be able to handle it? I'm currently running a Corsair 650TX 650-watt PSU that's powering a Radeon HD 5870 and an AMD Phenom II X4.

2. What sort of drivers will I need to make it work?

I don't think PhysX works unless both cards are nVidia now. There may be work-arounds but considering that not that many games use it and it hardly even makes a difference I don't think it's worth it.

Search for a power supply calculator. Preferable one with a known name behind it. Here's one. That should give you an idea of what kind of PSU you need.

I don't have any nVidia cards but as far as I know the standard nVidia driver should come with everything you need.

Serious? Is there a technical reason for that or are they just trying to pressure AMD customers into buying an extra card from them? Ah well, as you say a dedicated PhysX card is not worth it.

I've been told that that isn't possible.
You can use Physx but without the benefits of the Physx hardware and afaik there is no workaround to this.

Hmm, bummer. On a side note, I really can get this card super cheap ($20 USD) off someone. Would it be worth buying just to make a budget build around? I could use a media computer for my living room.

They also phased out support for the old Ageia dedicated Physx cards. I think the reason was that they didn't want to bother writing drivers that work in hardware that wasn't theirs but some people hacked the Physx drivers to recognize ATI cards as nVIdia and it worked just as fine. So the reason was that they are douches.
I remember that some people demonstrated that the PhysX drivers were made to run horribly slow on CPU too for no reason.

Answer below from Nvidia

Can I use an NVIDIA GPU as a PhysX processor and a non-NVIDIA GPU for regular display graphics?
No. There are multiple technical connections between PhysX processing and graphics that require tight collaboration between the two technologies. To deliver a good experience for users, NVIDIA PhysX technology has been fully verified and enabled using only NVIDIA GPUs for graphics.
