Should i dedicate a gpu to physx

The cards will operate independently of each other. SLI is a parallel processing algorithm for computer graphics, meant to increase the available processing power. There are also so few SLI users that when support breaks it takes forever sometimes never!

So SLI has nothing to do with cryptocurrency mining and would seriously limit you mining efficiency. But you could certainly use SLI in gaming and then disable it when you are mining. Minimum W or greater system power supply with one 6-pin and one 8-pin PCI Express supplementary power connectors. Notification Preferences. Forum Actions. Report Post. I'd use the ti if it's available.

The problem is when a user is running at higher display resolutions, causing additional load on the GPU thus limiting it's resources available for PhysX. At this point is when you want to have a dedicated PhysX gpu. In titles such as Batman and BL2 heavy PhysX based titles ; your performance would be about the same with or without the PhysX processor, though the ti would stabilize the frame rates slightly.

No, not "significantly", but will "stabilize" the few PhysX intensive titles out there. You would have to ask yourself if the increased power draw and heat generated by a dedicated PhysX gpu would be worth it or not to you. I do, however, recommend going SLI which would give you the best of both worlds. Thanks for the reply. I notice that some games especially CoD Ghosts suffers dramatic fps drops with PhysX turbulence for the smoke enabled.

I also see the fps going down on Metro Last Light when there are many particle effects. Helltech is also correct, I don't see GPU accelerated Physx being used more lately nor would I expect its usage to increase. Since Batman:AA came out a year ago only Metro has used it any worthwhile effect and you would need an insane setup to make it worth enabling.

The only game I've heard of in the near future that will use it in notable fashion is Mafia 2 and apparently you also need an extremely high powered setup to make it worth enabling.

Sorry I don't have a link to the article I read yesterday, but PhysX could be phased out eventually no time soon, though as the CPU takes over much more of the physics caluculations.

This is at the heart of the disagreement between Intel and Nvidia at the moment. Found a in depth review of Mafia II. It seems the game is highly optimized for physX and 3d. All sorts of comparison pictures and videos showing the added graphics.

There are charts and tests with multi gpu's , also dedicated physX cards. Turning PhysX off results in a hum-drum gameplay that resembles 3rd person shooters from the early part of the decade but with Ambient occlusion and higher res textures. I would rather trade graphical quality than play the game in its highest settings with PhysX disabled. It simply is just not the same game without the dust, debris, smoke and of course, the stylistic trench coats! Mar 6, 1, 0 19, Wow what is up with you people and PhysX?

It's garbage that deliberately slows down stuff your cpu can do by itself, in order to make you buy a crappy nVidia card at a higher price. PhysX sucks and always has sucked. Trueno07 Distinguished. Apr 15, 0 18, 1. Dedicated cards kinda went away when nVidia bought out PhysX. I find it more prudent to simply run SLI cards if you are going to go the "second card" route.

That way if you need more power in something other then just PhysX Calcs you have it. I thought they removed the PhysX features from that game because of performance issues? I was under the impression that they literally did go away when nVidia bought them SLI is also a "meh" solution too.

Try and find a single card that meets your needs, if for some reason there is no single card that meets your needs then buy two of them, if that doesn't work just keep adding cards ;. Ignoring the doubled cost of SLI, it's also going to suck down more power and generally you don't get the performance gain compared to investing twice as much money into a single card.

I have the other cards already wont be purchasing them especially for physx and the PSU is a watt corsair that is fairly new so I have the grunt there.

You can just dedicate a GPU to process only physics in the graphics card options if you have multiple cards. You'd be better off getting a second graphics card. The CPU does a great job of acting at the physx device.

And we'll assume that you have a W PSU to handle the entire system under load. Here are the benchmarks from Anandtech, and while they aren't perfect they should be a good baseline.

If you really want to push the limit then SLI is for you, but if that's your game why not just invest in multiples of the top card out there? At the end of the day, do what you want, but SLI really doesn't make practical sense unless you just so happen to have modern cards sitting around for some reason or another. Can't say much for others, but I have run into cases where people do Crossfire dunno if it works with SLI after upgrading.

If you have an R7 and upgrade to an R So I completely agree with you. However, if I were to upgrade and had the spare card still? Heck yeah I would keep it in there. Which is what I said in my first post. In these cases, your card is wasted.
