How would this card do as a dedicated physx card?

The price on that card and that it is short enough that it wouldnt block the intake on a larger card. I am building a new rig and I have not finalized on the parts but I will be running a i5 4670k definitely and either a gtx 770 or gtx 760. Any help is appreciated. Thanks in advance.

Really the GTX 770 or GTX 760 has enough performance that it could handle the Physx demand for the 20 or so games that even use it on it's own.

I guessed as much. I didnt plan on purchasing at the same time though. Since I dont have screens I would just be using a tv for now(which is when the 770/760 is ok by itself). My next batch of money though I plan on going triple monitor at 1080p and the was either going sli 760 at ~$500 overall or wait a little longer for a slight 770 price drop(sub $350) then sli that. Would the 760 or 770 experience any major frame drops though by itself in single monitor? I keep hearing heavy physx is a 20-30fps drop and can cause some stuttering for a few seconds in physx heavy moments, but I do not think I really care as long as the low average is still smooth.

What are your thoughts on that specific card if I do choose to have it as a dedicated physx/backup gpu?

You really don't need a dedicated Physx card, Physx doesn't take up that much power and I'm pretty sure the processing power required does not increase with resolution, SLI 760/770 would do it no issue. Plus, you'd also be shelling out like $200 for a few extra FPS in a library of 20 supported games.

It doesnt need it yea. I just dont want a massive lag when the primary is rendering something heavy plus its a heavy PhysX moment. At this point I would ride it out with just the 770 to see how it feels then get a dedicated if its not smooth enough. I also am going to play the crap out of the following with physx while probably trying the others later:

Arkham Asylum
Arkham Origins
Borderlands 2
Hawken
Lost Planet 2
Lost Planet 3
Metro 2033

This is a 20 hour investment per game on the low end for me. So I think having a dedicated physx card might be for me.

The card I was looking at was $130 and linked in my OP. I am actually mainly asking specifically how will that specific card do as a dedicated card.

EDIT:

I have decided I will go single monitor 2560x1440 and SLI the EVGA 760 2gb superclocked. While I understand that the motherboard must fit 3 cards if I add the dedicated physx card, but does it have to be 3way SLI compatible even though the last card wont be bridged with the other two?

Im running a GTX770 and have a 560Ti as dedicated PhysX.
770GTX on PLAGame benchmark
59.7fps

With GTX560Ti as dedicated PhysX card
102.8fps

Proof is in the pudding - it works.

I thank you for your answer but can you give me real world game numbers or point me in that direction from a 700 series (probably 760, 760 sli, or 770) with a 500 or 600 series card running ded.physx. The possibility of me doing 760 sli is the thing im mostly concerned about since thats the route I probably will take as an end result buying parts over 3 months or so to have a functional new PC for as low upfront cost as possible.

The build I want to end up with is in my signature excluding a custom waterloop based on external SR-1 rad and EK Supremacy waterblock.

Thanks in advance.
