GT 630 PhysX card any good?

[Bulge]

Got this old system with P35 mobo, 6GB RAM, and a GeForce GTX 650. Was wondering if I'd get gains from installing a spare GT 630 as a PhysX card. Any ideas guys? I play games like Tomb Raider and Batman Arkham.

I don't think that you would gain anything, but, if you already have the card, it would be easy enough to do the test.
