GTX 780 Ti with GTX 660 as dedicated PhysX card?

[Grug Son of Thog]

Hi all,

 

A friend of mine is upgrading his rig, and sold me his old Asus GTX 660 DirectCU II. I already have a GTX 780 Ti (also Asus DirectCU II, but that's irrelevant). I know that you can use older graphics cards as dedicated PhysX cards, and I'm considering doing that in this situation.

 

Here's my question; will this work in this situation, and how much of an improvement should I expect in game performance? (yes, I know it'll only work in games that employ PhysX).

physx isnt worth it a single 780ti would be more then powerful enough to but sure if you want your power bills to go up go for it

I have to agree with @ SAV1OUR

Well, I sort of live in a University apartment where I'm not billed monthly for my electricity use, so that's not a problem.

Should I just shove it into a new rig, then?

The 760 might not be able to catch up with your 780 ti so it might lose some performance instead.

It'll actually probably hinder your performance. Just use it as a standalone gpu in another rig or something. physX cards aren't really a thing anymore, and for good reason.

If you Play AC4 or metro LL, then you might get up to 15FPS more, but otherwise it is unnessary

Shove it into your rig and test the performance gains or losses and decide if you want to dedicate it.

Huh, okay. Well, I was planning to build a computer for my girlfriend, so I think I'll just do that.

There is literally no point in having a dedicated physX card. 

1. Nearly  no games use PhysX

2. It is going to use more power and produce more heat

3. it may even hurt your performance as the 780Ti will have to "wait" for the 660 to do the physX calculations and send it back.

 

The 780ti will crush any physX calculations you throw at it without even breaking a sweat.

Would there be any other applications for the card other than PhysX if I wanted to keep it in my rig? Mining, maybe?

Mining yes, but it'll run terrible and just be a space heater.

Have fun freezing to death during winter.

give it a try

I love when the AMD fans make this claim.

Or a more simplified list

http://en.wikipedia.org/wiki/List_of_games_with_hardware-accelerated_PhysX_support

Games running the Unreal Engine are the most common games to support Physx as Epic Games has an on going partnership with Nvidia.

OP, as other people have said, a weak GPU used as a dedicated Physx card is will not help. Your 780 Ti will do better on it's own.

29/10,000+ video games on the market. 3/1000. 1/333 of games

Also, most of those games are outdated and are easy to run on any modern system with PhysX on the CPU.

AMD Fan??

 

I'm running 2 GTX680's in SLI, and my second PC has a 550ti.

 

Don't get me wrong PhysX is a great idea, the only issue is that it will never be implemented across the board in every game (because it will only work on Nvidia GPUs).

 

Also I still stand by my statement that "Nearly no games use PhysX". In the Wiki link you posted there is a mere 55 games since 2006 (8 years) that use PhysX. 

 

In 2013 over 50 games were published just in January and February alone.

 

http://en.wikipedia.org/wiki/2013_in_video_gaming

 

Lets be conservative and say that about 15 games are published every month for 8 years that's 1440 games (keep in mind this is an estimate and does not take into account the recent rise in indie games and mobile games).

 

So in that case, only 3.8% of the games published in the last 8 years support PhysX. 

 

I support Nvidia and their innovation, and i would love AMD, Nvidia and the game devs to work together, but that is never going to happen (well not on the scale that gamers want it to).

Long story short: Let the 780Ti do the PhysX (if even supported by the game), sell the 660, and treat yourself to a nice dinner or something.
