Will a separate PhysX card help a GTX690?

[TheGreatSatan]

I have a GTX 690 and actually have considered buying a second:santa:

I was wondering about a separate physX card instead. Would a 560 Ti or 660 Ti help at all, or is a single 690 overkill for any game as it is?

I would say nope, it would slow things down if it had any affect at all.

But I am more than certain that you could pull a card from somewhere to test with so there is no harm in trying and running a few benchmarks physX and non physX alike.
So I don't see any harm in trying.

What games do you play? Very few will make use of a dedicated Physx card.
