Hey guys, I was wondering if 560ti run as a dedicated physx more than enough for all the games out today? Also, I was wondering what is the best card for dedicated physx as well?

You would be absolutely fine with GTX 560ti Physx card. It can run every game that has physx enabled very well. Not all games use physx by the way. Best card for physx i would recommend 8800GTX or GTX 260 as they have wider memory bus. Physx cards don't require as much GPU Power all they need is memory bandwidth and Wider memory bus so any card that has good amount of memory bandwidth is fine for physx.

Thank you very much for your input. But, I did clearly state that I have a 2-way sli 770. I was just wondering how I can utilize a boost in physx to run games like Metro.

Your title was a little easy to misinterpret then, so I apologize.

If that's the case... your dual 770s should be able to handle the PhysX just fine without the 560Ti. Just be mindful that some motherboards with 3 PCI-Express lanes will bottleneck the other lanes.

For example, the MSI Z87 GD65 board has 3 PCIE Lanes, that runs in the following configurations (and so do a lot of other boards):
16x for one card
8x/8x for two cards
8x + 4x/4x for three cards.

Notice how your bandwidth for two of your lanes suffers significantly with the third card in slot. You may want to consider looking into this before adding in the 560 Ti with the 770s and potentially robbing them of PCIE lanes.

This is the Mainboard that I have. It would run the dedicated physx at 8x right?
