I just dropped a new card in my rig and am wondering on what to do with the older cards I have that are currently being used, but not required in the machine they are in.

My current rig:
Asus P8Z77-V Pro
Intel i7-3770K @ 4.24 GHZ
MSI GTX 670 N670GTX-PM2D2GD5/OC (314.07)
G.Skill Ripjaw 4x4GB DDR3 1600
Corsair Gold AX850 PSU
Mitsubishi 52" LCD (1080p)
Win7 Ult x64

The cards I have access to that are in other rigs that aren't used for gaming are

GTX 470
GTX 280
9500 GT
8600 GT

I'm wondering if I should use one of those cards as a PhysX processor on this rig.
Reading all over the place and some say it's worth it to add the card, others say don't bother.

As the max resolution on the monitor is 1920x1080, that's what I set everything at and usually crank everything up.

Are there any recommended apps or in-game benchmarks that I could try out the different combinations and see if it's worth it or not?

PhysX is only useful for eye candy and even games that do make use of it (Crazy Machines 2), it has to work with the CPU path anyway. Is it nice? Sure, all that debris in Borderlands 2 was a nice touch. Is it worth while? Not really. Especially for some of those cards that will chew up over 100W.

If you really want it, stick the 9500GT in there and dump the others.

Thanks LatiosXT,

I was leaning towards the GTX280 or the 9500GT as the card to use, but not sure what would be more useful.

The 670 is a powerful card and nVidia's software may opt to use only that card to handle both graphics and PhysX, so you'll have to modify the settings to use a second card for PhysX.

I had a 9600GS as a PhysX card in my rig and the best I could get was medium settings. With the PSU you have, I would move up to the 280 or the 470, whichever consumes the least power (though you should have enough for either).

Hope this helps.

Thanks btdog,

I think I'll try out the 9500GT and the GTX280 and see what / if any difference there is.

Are there any benchmarks that actively incorporate physx in the benchmark process so I can see if there is any benefit, or what the difference is between just the 670, and when adding in the 9500/280?

It's more for my own edification than anything else.

Those are the games with PhysX support, though I don't think any of them have a standard benchmarking tool. The one game that did run slower than what I'm usually used to surprisingly was Borderlands 2 with the PhysX cranked up.
