    Silly question..

    Can you use the i72600k's GPU for Physx or does it have to be an Nvidia chip

    Have a spare 580GTX and was going to use that, unless .......


    No need for sarky comments, just a yes you can or no you can't will suffice :)


    Thanks Chaps & Chapettes

    Nope purely Nvidia cards for Physx.

    Would you count "l will take that SPARE 580 off your hands" as sarky? As I am really willing to help clear some desk space for you. I'm that nice.

    Even if you COULD, the Intel graphic solution won't be able to handle it. Well it would be CPU based really, as Intel graphic solution is still depending on the CPU, and doesn't have a dedicated processor like Nvidia's or AMD. While it will work, you are better off purchasing a 25-35$ Nvidia GPU for this. You are most likely going to get more performance over Intel's.. IF it worked on Intel.

    The problem with PhysX is the fact that it's hobbled for CPUs. If not it would be great. The best alternative? Grab a GT430 or something similar and offload physX on that. But it's debatable if that's even worth it.

    Just SLI those 580s!

    mafia 2 looks awesome with physics but its a huge performance hit for what it does.

    Yeah, an 8800GT would do for PhysX, a 580 GTX for PhysX is a total waste.

    Buuutt, leaving a gtx580 unused is a total waste too!

    For a few of the newer games an 8800GT would give you a decrease, Fermi cores are much more efficient with these calculations. I've done a few benchmarks to prove it with my old 9800GTX+ slotted alongside my current 560TI.

    I know Arkham Asylum would dynamically drop GPU Physx calculations on the fly if it didn't have enough shaders to calculate them on, I'd expect Arkham City to do the same.

    Having powerful enough Physx card would make for smoother gameplay so long as the main graphics card can still maintain full PCIe bandwidth or has a lot of memory so it doesn't need to swap data and textures to and from off the system memory.

    I used to find it handy to divide my graphics power in my old SLI system if I needed to dedicate one of the cards to Physx calculations.

    I'm not saying that a 580 is the ideal solution but if you already have one with a PSU able to handle it (not that Physx calculations draw much power compared to the main GPU) and you play games with PhysX enough then it might be worth putting it in.

    IIRC in mafia 2 , you really wanted at peast a 9800GTX for physx , ideally a GTX 260

    I think Mafia II was one of the games that slowed down when I tried my 9800GTX+ alongside my 560TI

    Edit: either that or the minor improvement wasn't worth taking up half my PCIe bandwidth for.

    I have a Asus GeneZ68 with a slightly oc'd 2600k around 4.2 ghtz Will be picking up a 690 today and of the 580, Using a 1000w modular PSU (think its a Corsair one, I forget) SSD and two mechanical HDD, a Pump (laing D5vario) and 9 fans

    I am assuming the 1000w will be sufficient for running the two GPU's ..ah well if its not I'll see later I guess huh

    You might find it's possible to configure the card to use 1 of the gpu's on the 690 for Physx when you need to.
