No you cannot, to SLi the GPU's must be the same.
Thanks, I have no idea about SLI, have never done it before
you could use the 660ti as your main GPU, and use the 650ti B as a dedicated PhysX card. But it's one hell of an expensive PhysX card!!
You would need to make sure you have a big enough PSU to power them both though, along with the 6/8 pin connectors which would be required for both cards.
it is an option though.
That sounds really interesting, unfortunately I have no idea what it means. How would that work?
Well, to start, list your full system specs, and we can see what's what. As I've already outlined though, and mousemonkey has alluded to, it will be one hell of an expensive PhysX card. Mouse monkey is also correct, PhysX doesn't work in all games, there are only some that use it. But those that do, look so much better.
here's the list of games that support it.
http://en.wikipedia.org/wiki/List_of_games_with_hardware-accelerated_PhysX_support
Out of that list, I play maybe 6 of those games regularly. Batman Series, Borderlands 2, MOH Airborne, Mirros Edge, Metro 2033, Tom Clancy too.
So unless you play some of those games in the list it is a waste. But if you already have both GPU's then, Id be giving it a go, if it were me
The main thing is you need to have a motherboard capable of sli ( so you have two slots)and a PSU with sufficient power to keep both running. And as I've said above the PSU must have 3 x 6pin power connectors.
But it's doable, has some performance increase, it looks pretty in games tha use it, and the list is growing too, albeit slowly
