Need help finding another card to pair

[aviavy]

Hi,

I'm looking to do some upgrading soon.
I currently have an Evga 560Ti 1GB and I want to pair it up with another card.
I have always been told to pair your card with another of the same chipset, but as I am researching, I am seeing a lot of systems with 2 completely different chipsets.
I recently got Batman: Arkham City and in the setup for PhysX, it recommends NVidia Geforce GTX570 + Dedicated GTX 460 or better for the high setting.
I was thinking of getting a 660Ti if possible.

So given this, what do you guys advise/recommend?

In case it matters, I am running the following:

MB: ASUS P8P67 Deluxe
RAM: Corsair Vengeance 2x4GB
Video: Evga 560Ti 1GB
OS: Win7

Also I plan on getting Hitman: Absolution & Assassin's Creed III, so I want something nice to help truly optimize the video.

Thank You In Advance!

For SLI you need another 560Ti any brand.

What is the difference between SLI & having 1 card dedicated though? Pros? Cons?

SLI is both cards working together and makes a more powerful setup. A single more powerful card is the choice of many including me.
