Will be using it as dedicated physx card in Witcher 3, CoD Ghosts, Batman games (all 3), and a couple others. how about this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130788
I think you will do just fine with your SLI setup. Check my score with Batman AC and im on one Oc'ed 570GTX. http://forums.guru3d.com/showpost.php?p=4680411&postcount=277 http://forums.guru3d.com/showpost.php?p=4680433&postcount=7 Ps Witcher3 and others will use physx3, which is a lot faster (better optimized) compared to older physx2.8 like in BatmanAC, etc. And that 610GT will be too slow, your SLI setup would be faster alone, if you still want then get at least http://www.newegg.com/Product/Product.aspx?Item=N82E16814127703 or http://www.newegg.com/Product/Product.aspx?Item=N82E16814130796 In this case you can get that msi for 75$ and it will be faster because of higher vram bandwidth., although that single slot design looks handy too. http://forums.evga.com/tm.aspx?m=1768879
It's a waste of money and power to run that card you would need at the minimum say a 650 to see any improvement over what just your 760 sli does. Short version don't do it.
I remember for a 580 you needed atleast a 560 as PhysX Card to get a performance boost. So i guess you will need something like a 660 (Ti) atleast to have a positive effect.
tried it out myself. only game i found it to be worthwhile was mafia2, that showed a nice increase to fps. borderlands 2 didnt seem to like it. i dont think it's worth it but give it a go, you can always send the card back.
Agreed with spets. I would just use 1 of your 760s as physx. Not dedicating it to physx alone. You would get a boost buying a dedicated physx card but I personally would not bother
If you do decide to use a dedicated card, look for a used GTX460 1Gb 256-bit version card. I picked up two of them from E-Bay several months ago really cheap. Put one in my son's and my computer.
I wouldn't get anything less than a GTX650. Mine gets up to 80% usage, that was with a GTX680. If you look at PhysX comparisons, gpu clock speed makes a big difference. I saw a chart that had the Superclocked GTX 650 @ 1202Mhz beat out a 680 at stock speeds dedicated to PhysX, I believe they were paired with another 680 for rendering. That was because at the end of the day the 384 CUDA Cores on the overclocked card were more helpful.

GPU clock speed makes a difference not only in PhysX, but gaming in general imo, especially if you use the setting max pre-rendered frames '1'.
