dedicated physx card

Im going to buy another gpu for dedicated physx and was wondering would something cheap like a geforce gt 610 be up to the task or would I need something a little more powerful.

A GT 610 will actually decrease the performance of a higher-end GPU when used as a dedicated PhysX card. It's pretty much never worth it to have a dedicated PhysX card nowadays, just leave it as it is.

what do you do that you really need a second gpu just for PhysX?

@OP listen to this.

 

i have a gtx650Ti i used to use as a dedicated physX card, it slows down other cards, don't get a physX card, add another card to SLI or don't add a card at all.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

If you have to buy a PhysX card then don't. Just save up and do SLI the performance increase will be much better. If you have an old card you can try it but often they aren't worth it. I ran a couple of tests using a 680 (half of my 690 disabled), a 690 (680 SLI), a 680 + GTX 260, and 690 + 260. While the 260 did actually improve frame rate slightly it wasn't worth it unless you already have an old card, and that old card isn't horrendously loud.

Thanks for the reply's, it looks like i wont buy another card. I am already running 2 970's and they are not that good. Major problems with gpu usage and low fps and they scale like crap. And when i say crap i mean it, 30% boost max.

Anyway thanks for the reply's. Great help.

Out of curiosity what if you're running team red for GFX? Is it possible to have a budget tier team green do PhysX?

1. Overclock until the magic smoke comes out. 2. Modify until broken. 3. Fix and repeat.

Say I have SLI 970, is my second 970 dedicated to PhysX or are the cards sharing it? Is that even possible? If not, which card is using it? Also would it be worth it for me to put my 660 in my PC as well dedicated to PhysX?

Yes you can have a separate Nvidia card but the bottleneck precautionary still applies, too slow of a GPU running PhysX will actually reduce performance on higher end AMD cards

The two cards work in combination, so the two cards are sharing PhysX calculations (in games that support SLI).

 

No, with SLI 970s its not worth it to use a 660 for dedicated PhysX. You'll get pretty much the same performance (if not slightly less) but with added power consumption and heat output.

Huh, interesting. I wonder how you'd go about finding the right level of performance without throwing money around like water. I know it's generally a silly idea, but curiosity is a strange beast.

The technical answer is yes, the practical answer is no. You can not easily run an AMD GPU with a Nvidia PhysX card. Even if you do get it working it works on 4 games. The mod lost support 6 years ago. Here is the information for how to use hybrid physix.
