i use a 9800gt and it works fine and i see a modest increase in frames, you dont need anything super powerful especially since it will get very limited use

What is the point? Two GTX 580s don't need dedicated physX.

If you have more cash to blow just get a 3rd 580, it won't scale amazingly but atleast it would give you benefits in most games, rather than just the 3-4 "GOOD" physX titles out there..

You don't need dedicated PhsyX to max out PhsyX titles. Even my single GTX 580 doesn't have issues maxing them out.

Try and find a cheap GTX 260 on the OCN Marketplace or eBay and you'll be set.

i have a 9800gt for physix, it runs everything smoothly, and only have dips because my card(4870x2) was going. other than that, it works

GTS450 is the max I think is really needed for the 2-way SLI.
A stronger one will give a few extra FPS, but its not money well spent.

look at these numbers! You will get a big adavantage , but only in games that use physx. With two gtx 580, they should handle physx pretty welll all by themselves!

I personally don't like running physX on my SLI set. PhysX only runs on one card, and it throws the balance off, gives you weird GPU usage and just doesn't 'feel right' to me. I prefer, when playing physX games (Batman AA, Mafia 2, and Mirrors Edge are the only one I've cared about), to break my SLI set and dedicate one card to physX. The gameplay just feels a lot better to me. And in this config I can still max out BMAA (w/8xQAA) and Mafia 2 just fine, so I'm sure a 580 would have NO issues doing it.

If I were you I'd skip the dedicated card, and do what I do, at least until such time as a hardware-physX game comes out that single 580 can't max by itself w/the other dedicated to physX.
