GTX 1080 Gigabyte Xtreme + Gigabyte G1 GTX 970 Dedicated Physx

post #1 of 7
Thread Starter 
Hello,

I wanted to hear others thoughts on whether or not keeping my 970 as a dedicated Physx card would be worth it. I just bought the 1080 and it should be in either Saturday or Monday. I do not know what I want to do with the 970 at the moment, I wouldn't mind selling it, but if it is worth it to keep as a dedicated card - I will keep it.

I am running 2x 1440p monitors (a Qnix, and a brand new Dell S2716DG @ 144hz) and an old Samsung 1080p monitor.

I mainly play WoW, LoL, CS:GO and many games coming out soon appeal to me, especially BF1.

I think the only way to get a definitive answer here is by testing it yourself, with and without the 970. I will tell you though that if the games you play don't use NVIDIA PhysX (I don't know which ones do and which ones don't without Googling it), then the 970 will just be sitting there idling dumping a little bit of extra heat into the case and consuming a little bit of extra power for no good reason at all.

 

Also, the days of needing a separate PhysX processor (or, the days of benefiting from one) are long gone.

Thanks for the fast reply, I mise well test it out when I get the 1080. After reading around a little bit it seems not many new games use phsyx - so it might be useless to keep. I will try it out and if I don't want to keep it around- I will try to find someone to sell the 970 to.

You "mise well test it"? Huh? Did you mean "I might as well test it"? I'm just asking for clarification, don't mind me.

 

Anyway, yeah PhysX seems to be dying out. However, some brand new games are using it, like a new one that I'm all excited about called EVERSPACE. It's still in development. So, I don't know.

I don't think any of the games you listed support GPU/Hardware PhysX (or even CPU PhysX at all for that matter, most use other physics engines), thus a dedicated PhysX card won't do you good for those.

Many people aren't aware that "PhysX" only describes Nvidia's PhysX physics engine/framework. Many mistakenly call all physics engines "PhysX", which isn't right, as those aren't normally GPU accelerated.
Also, there is CPU phyiscs and GPU aka Hardware physics. The former only utilizes the CPU and thus a dedicated PhysX card won't do any good there, while the latter only works with a dedicated PhysX card.

That said, a 970 would likely be a great PhysX card in combination with a 1080 as a main GPU. I myself am currently running a GTX 1060 Mini as dedicated PhysX card to support my Titan X (Pascal). This combination works really well in games that support GPU PhysX like Batman: Arkham Knight. In that game only with the dedicated PhysX card my minimum framerate stays around 60FPS at 3840x2160 with maxed out details and Gameworks/PhysX effects enabled. With just the Titan X handling the rendering and PhysX, the FPS drop down into the lower 40s during PhysX heavy scenes which causes unsmooth gameplay.
So yeah, a dedicated PhysX card (if powerful enough with enough CUDA cores and ROPs to handle physics efficiently enough) can immensely help with performance in games that support Hardware/GPU PhysX, but it all depends on the game as well.

That said, not all that many games support GPU PhysX, so it isn't really worth it if your favorite games don't. You can check the list of PhysX enabled games here to see if anything you like to play is on it.

Let's not confuse anything here, a dedicated PhysX card isn't needed for games that use hardware PhysX. GeForce cards have been able to handle everything for a VERY long time now.

I have been using SLI 970s and a GTX 480 now GTX 580 3GB for Physx. Like two cables said. Unless the game uses Physx like Metro or Hawken, Borderlands 2 and such it won't be used. My 580 only sees maybe 14-20% load max settings@2560x1440 in Metro 2033 Redux. Just make sure in Nvidia CP that you have it set to dedicated Physx on 970.
