    Hello, one more time.

    All day i tired to run 4870x2 as main card and 9800GTX+ as physx and nothing worked :bawl:

    Can some one be so kind and explain me how i can acheve this?
    I'm not that good with ATI cards/drivers :/

    i tried to fallow this tutorial and it din't worked... :/

    Can it be cause i try to do all this on SLI motherboard?
    Can it be cause i try to do this in Vista 64bit?

    Can someone please help me to run 9800GTX+ as physx?


    Thanks in advance! :)

    Vista only allows a single videocard driver. Mixing Nvidia and ATI only works on XP and 7.

    I also thought you needed a lucid hydra chip (opposite of nf200) to mix ati and nvidia cards

    thank you so much "teleguy"

    everything is working on Windows 7 :)

    i have one last question, how i can get physx tab to show up in nvidia control panel?

    because its not there. GPU-Z shows that Physx are ok/working

    ppl have been using nVidia cards for Physx with Ati Cards, for years.

    There is just a hack for it, no need of anything else .

    That's if you want to use both for rendering. Lucid Hydra has nothing to do with Physx.

    it was working good for a day, after then my 4870x2 died... i think vram was overheating and i started to see lines on screen even in bios..

    so i got my money back and got my self a GTX280 AMP Edition from Zotac

    its kinda sad that my 4870x2 got damaged... it was a really nice card.

    Now i have GTX280 and 9800GTX+ for physx :) can't complain about it, games run very nice, now even Shift 2 runs on max settings without any problems, cause i had much troubles with 9800GTX+ SLI and Shift 2, performance was really bad..

    Still thanks everyone for help just too bad i cloud enjoy 4870x2 performance for as much as i expected :/

    IF You had the option you must have gone for a GTX460 or GTX560 instead that GTX280
    and Just overclocked it a little .So you could enjoy ِDx11 . by the way GTX280 is still a
    good Card but I hope you get a good deal on it as I heard that in some places they are selling them very cheap to empty their stock

    that 4870x2 was used card(cheap price tag), tho it was clean and looked like new. i got it cause its performance was better than 98000GTX+ SLI, too bad that card died... but still i got my money back and bought a GTX280 from a friend, also cheap!

    in my country everything have a very high price tag unless its used...

    taxes are like 21%...

    i'm thinking to go for GTX280 SLI or GTX560Ti but 560 SLI will cost me lots of $$$ :/


    i don't play (at this moment) at HD resolutions, i play at 1440x900 19inc widescreen monitor so GTX280 is enough for me :)


    EDIT:
    Here is a price comparison (in my country) New vs Used
    New - GTX285 1GB = ~520$
    Used(perfect condition) - GTX285 1GB = ~160$

    I'm kinda thinking you believe Shift 2 is running better because of 9800GTX+ being dedicated to PhysX. Is that it?

    There are two kinds of PhysX, so to speak: the "GPU Accelerated PhysX" and "Software PhysX". The first is implemented through CUDA cores only, therefore, needs an nVIDIA card to run properly.

    Shift 2 has "Software PhysX" implementation which can be run by any card, ATI/AMD included. Having a dedicated PhysX card will not have any performance impact in that game. Remove the 9800GTX+ or disabled Accelerated PhysX and Shift 2 performance will be the same.

    Only games like Batman: AA; Metro 2033, Cryostasis, Dark Void, Mirror's Edge, Alice: Madness returns and a couple of other VERY OLD titles benefits from having a dedicated PhysX card.

    You have now a good performance NOT because the PhysX card BUT because you aren't in CF anymore and GTX280 is a good DX10 card. I had same issues playing Shift 2 in CF sometime ago, too.

    Sorry if I'm bringing you old news and you already know this stuff but, the way you wrote things before made me wonder... :p

    lol, i know all this, still thanks for your time :)

    i tested 9800GTX+(physx) with Mirrors Edge :) works perfect :) (if there will be a good SLI support for Shift 2 i think 98GTX+ in SLI should perform even better than a single GTX280)

    i added 9800GTX+ for physx because it was laying around doing nothing :D

    LOL, yeah as I suspected... You are welcome. ;)

    I understand. Is very much what I did with my GTS250 :)

    My question/doubt is if you really have performance gains with a dedicated 9800GTX+ over the GTX280 running PhysX alone. I mean, the 9800GTX+ has 128 CUDA cores -- same as GTS 250 --, and the GTX280 has a lot more cores, almost doubles it: has 240 CUDA cores. If I were you, I would run some PhysX tests and benchmarks just to be sure the 9800GTX+ isn't bottle-necking your GTX280 in those applications/games using GPU PhysX.

    If I could find a good used 9800 GTX I'd get one to run with my 4870x2 (and futuire 7000 series card) ... but I can't seem to find one.... ;-(

    The best I can find where I live is an inno3D 9800 GT that the guy is asking ~85 $ for and claims is in the original package and has never been used (which is probably a bunch of bullsh1t).

    What do you guys think?

    @shimyns, get a GTS250 :)

    @Johnny Rook, in Metro 2033 - High,Physx on, all AA set as high as possible,DX10, 1400x900 i get avg 36-38fps

    dint tested running only GTX280 but i'm going to! :)

    EDIT:

    running Metro 2033 with 9800GTX+ SLI on Very High,DX9,Physx off, all AA set to as high as possible at 1440x900 i get ~36fps :D

    EDIT:

    Finished those benchmarks...

    Options: Resolution: 1440 x 900; DirectX: DirectX 9; Quality: Very High; Antialiasing: AAA; Texture filtering: AF 16X; Advanced PhysX: Enabled; Tesselation: Not supported; DOF: Not supported

    Average Results
    Average Framerate: 35.33
    Max. Framerate: 91.84
    Min. Framerate: 8.95

    GTX280 + 9800GTX+ Physx

    GTX280

    as you can see this time i used DX9..

    there's absolutely no difference in performance....

    what should i do? take out 98GTX+ and let her collect the dust?

    Thanks, I'll look into a GTS250. The cheapest I've found a new one for is ~110 $ here by inno3d. I'll keep my eye out for a used one.
