Ok I did two more tests on physx one with a dedicated physx card and one without. The results are... well ill let you decide
 
metro benchmark
no phx card=39fps
dedicated phx card =42fps
 
 
mafia II benchmark
no phx card=46fps
dedicated phx card=44fps
 
As you can see the results cancel each other out

    Hum, I'll have to pop one of my 450's into my rig and see how it does with a dedicated PhysX card and a GTX 580.
     
    Last time I did a dedicated PhysX card test it was with two GTX 465's in SLi and all the scores were improved using the GTS 450 SC.

    I've heard at least a GTX 285 or GTX 460 is needed for any significant gains with a GTX 580 with dedicated Physx.  It is due to GPU Physx processing cycles need to keep up with the GTX 580 cycles in actual game performance.  Otherwise, the GTX 580 just handles the Physx and ignores the lower cycles of the dedicated Physx card

    Well, you have heard it all wrong. Using a 8800GS for dedicated PhysX with my system improves performance in mafia II and Batman AA as well as Cryostasis. PhysX processing "cycles" have nothing to do with what the GPU for rendering graphics is doing. All the PhysX card is doing is calculating the trajectories of debris, rocks, smoke...ect. And furthermore, if you dedicate a card to PhysX the primary GPU does not just automatically ignore the dedicated PhysX card if it deems it too slow. Where did you hear that nonsense?
     
    As for the OP, what cards and what drivers? You don't really give any useful "data".

    You gained 10fps on the Min fps with a dedicated 450 - nice

    Ya, all the answers to the OP in that thread were on the 'assumption' a GTX 580 was already installed.  So thanks for setting me straight.  Personally, with my setup, I would rather keep air flow and a dedicated Creative xFi card than go with three slots with GPUs.   But if I had just one GTX 580/570, I would have my head more in the gameplan

    Sry, but I just noticed your SLI'd.  No wonder your dedicated physX card isn't producing numbers to any real effect.  The 480 SLI systems had the same problem of no real world gain with a dedicated card.

    I got about 3 extra fps when I benched Metro using my 260 as a dedicated ppu, and I also got some goofy numbers when trying to bench Mafia II. EVGA now has my 470 and I should be getting my stepup 570 next week and will get to play with benchmarks all over again.

    It's something absurd you gain with Mafia II with a dedicated PhysX card as well, but I don't have it installed at the moment, and I don't feel like downloading it again through steam to make a point that I already know to be true. And that is in games that support GPU PhysX having a dedicated card for PhysX will benefit you greatly. And no it doesn't need to be a hugely powerful card. As my pics above illustrate even a lowly 8800GS with 96 cores will make a significant difference with 3 GTX480's in GPU PhysX enabled games when using it as a dedicated PhysX processor.

    Okay, so just let me get this straight one more time.  If I have an 8800 GT as my primary card and I used a GTX 580 Superclocked as my PhysX card I shoud see improvement with my PhysX enabled games, right?  Like 10 FPS or maybe 12 FPS, right?

    Umm well your first post doesn't make sense for Mafia II You should have seen a decent increase in frame rates in Mafia II.
    On the other hand, Metro 2033 runs about the same for me running TRI SLI or SLI and one dedicated. As soon as my step up 580's get here this coming week, I'll run some benches with SLI 580 with a 470SC for PhysX. That should produce some killer results.

    Some things to consider.  Hemi's TRI is not optimized for games - only benchmarks.  Also TRI produces a HELLALOTTA heat unwarranted in a PC Case for the average gamer like me just wanting to max everything out on any game.  Two GTX 570/580 will do that.  Why tax your MB/CPU/RAM/HD/SSD/GPU etc...(and stress them) just to get no real gaming FLOW performance. 
     
    I am not speaking to the King of the Hill benchmarkers, just to those of us peering to see what the King of the Hill is looking at and enjoying his conquest without dethroning his superiority over the rest of the gaming world.
     
    Unless you haven't learn the Happy Days Fonzie Lesson (that he's defunct with nothing to show for it) then observe that VALUE point, ponder upon it and either piss on it and/or consider it for what it's worth.
     
    Also, nVidia doesn't optimize TRI, but is hellbent to optimize SLI.

    I am running 2 Evga gtx 570 sc in sli and decided to throw in a Evga gtx 260 as a dedicated Physx card and wow, things got hot. I only ran Vantage before taking it out due to peak temps and the results were worse then without. I don't know if thats just because Vantage doesn't take advantage of a dedicated card but either way 20c hotter on my primary card isn't worth 10fps in select games.

    EVGA Has Lost What Used To Be A Lifelong Customer! I no longer will buy, support, work on, or build rigs with ANY EVGA Product! I will also not be building or working on any others that I build for others with a EVGA product, and will be telling them why!

    Interesting to see how much of a difference that phsyX card really makes.

    Wow, both T_Flight & sk2play, are both horribly ignorant and just refuse to understand anything shown to them.
     
    Lets get a few things straight shall we? First of all Tri SLI is optimized just fine in the vast majority of games released today. And actually Tri SLI scales rather well especially as resolution increases. 3 way SLI is intended for people that use high resolution and can use the extra performance. Personally I game in Surround at 7920x1600 and the 3rd card adds significant performance to my games. But who wants to believe me right? Lets find a review from a reputable site shall we?

    GTX580 3 way SLI review:
    http://www.guru3d.com/art...-580-3-way-sli-review/
     
    And lets just make that easier for the kids here since I'm sure we're not dealing with the sharpest knives in the drawer here

    http://www.guru3d.com/art...580-3-way-sli-review/9
     
    Oh my, what do we see there? Looks like rather good scaling in 3 way SLI. Lets look at a few more popular games shall we?
     
    Battlefield BC2

    Do you notice a trend? As resolution increases, so does the percent gained by 3rd card. In fact you'll see that trend in the majority of the games they test. Saying that 3 way SLI is not optimized for games or that Nvidia doesn't optimize Tri SLI is honestly just uneducated. Of course there are some games that don't play nice with Tri SLI, just like there are some games that don't work well with 2 way SLI. It comes with the territory, but in MOST games it works fine.
     
     
      And as for 400 series owners not having any experience with 500 series cards, that's really just one of the dumbest things I've heard in a while. Both cards use the same architecture (Fermi) and what applies to one, will apply to the other. If both are used with the same driver, both will show roughly the same percentage gains and trends between them. Of course the review above isn't using the same driver, yet still yields strikingly similar gains in the games tested in regards to performance and scaling. What does that tell us?
