Physics Card - Is it worth it?

What are the pro's and con's of adding a dedicated physics card?

I have an open PCI Express 2.0 x16 slot and I was thinking about adding a single slot 9500GT 1GB ( http://www.microcenter.com/single_ [...] id=0295225 ) as a dedicated physics card to go along with my 9800GTX SLI configuration. Would I see a benefit in adding the card or just a waste of money. The main games I play are COD4, CODWaW, Tiger Woods 08, Medal of Honer Airborne, Need for Speed Undercover, and a little Crysis ever now and than.

Thanks for your feedback!!

You'd have to know what to look for in terms of physics (it's not something that can be seen as easily). As for the games, you'd want to look at games that support it and then also to what extent. But even then I don't see any worth in it - think for a minute and tell me where would you really like to see more advanced physics as opposed to what you are currently seeing? Then think what dedicated physics should in ideal terms bring: isolated cases of "hardcore" physics or larger scale physics application.

Thanks for your feedback....

I was leaning toward that it doesn't add much benefit but I have an open PCI Express 2.0 slot that I could've add another card to, so I want to see if it was worth it since my board doesn't support 3-way SLI. Don't know why you have 3 slots and don't support 3-way SLI but who really understands why manufacturers do what they do.
