You could also use it for F@H when you're not gaming on it, or if the game you're playing doesn't support PhysX.

Should try GTS450 + 2x 6950 or GTS450 + 2x 6990
You could get away with GTX460 and overclock it a bit will be better than stock.
Let me know if you need more info.
Yeah, unfortunately that seems to be the catch-22 of PhysX cards: they don't have to powerful, but they do need to be fast. A 470 is overkill for PhysX calculations, but is needed if you want an actual FPS *increase* when paired with powerful cards. If you're fine with losing a couple fps to get the extra eye-candy of PhysX, then I think you'd be fine with a cheaper card, and worth it IMHO. (I'm looking into getting a GTS 450 as well).
As long as you're aware that there are only about a dozen games that utilize PhysX.
EDIT: Here's a look at how different 400-series cards perform when paired up with a single 6970 or 6870 in Mafia II, which seems to have become the standard PhysX benchmark since it seems to use PhysX the heaviest.
