    Hi just wondering which card to get that will run physx on max phys settings on borderlands 2 with eyefinity setup without any slowdown and decent enough framerates, planning to run along side 6990 dont want to spend a whole lot also heard you can hinder performance if going for a too higher card unless your using it as your primary card.

    I don't know about eyefinity but I used they below information and purchased a GTX650ti

    I’m back – this time pairing my GTX 690 with several Kepler card variants to determine the best PhysX PPU for the buck. The test beds: Borderlands 2 and FluidMark.
    [​IMG] From left to right: GTX 650 Ti, GTX 650, GT 640, and on the bottom, the GTX 680.

    Test Rig Details:
    i7 3820 @ 4.5 GHz (1.40v) / EVGA GTX 690 (1148 MHz boost, +400 Memory, 135% Power) / 32GB Corsair Vengeance DDR3 1600 MHz / 512GB Samsung 830 SSD / Seasonic X-1250 / CM Scout 2 Case
    [​IMG] Total PhysX Overkill! [​IMG]

    Windows 7 Ultimate with SP1 and latest patches (10/15/12) – x64
    NVIDIA GeForce WHQL drivers 306.97
    FRAPS 3.5.9
    Game / Benchmark Details:
    Borderlands 2 / Steam / Updated on 10/15/12
    All graphics details maxed (PhysX: High) – 1080p (1920×1080), 120hz monitor
    FluidMark 1.5.0
    Testing Methodology:
    Configurations:
    EVGA GTX 690
    EVGA GTX 690 + EVGA GT 640 (dedicated PhysX PPU)
    EVGA GTX 690 + EVGA GTX 650 SC (dedicated PhysX PPU)
    EVGA GTX 690 + EVGA GTX 650 Ti SSC (dedicated PhysX PPU)
    EVGA GTX 690 + GTX 680 (dedicated PhysX PPU)
    Game / Benchmark Scenario:
    Borderlands 2: Bloodshot Stronghold – first 3 waves of enemies (each configuration tested 3 times, results averaged).
    FluidMark: PhysX Benchmark Preset: 1080p (each configuration tested 1 time). NOTE: FluidMark is not SLI aware.
    Results:

    GT 640 3265 54
    GTX 650 4096 67
    GTX 650 Ti 4711 77
    GTX 680 4472 73
    Borderlands 2
    Average FPS Avg. FPS Gain Minimum FPS Maximum FPS
    No PPU 96.48 - 63.33 172.33
    GT 640 102.29 6% 51.67 205.67
    GTX 650 112.77 17% 62.33 210.00
    GTX 650 Ti 106.82 11% 69.67 239.33
    GTX 680 109.10 13% 67.00 185.00
    Conclusion:
    Borderlands 2 continues to be a bit baffling. Throwing a GTX 680 at it as a PPU does not yield crazy results – but a GTX 650 does surprisingly well. My hypothesis? Clocks matter. The GTX 650 SC from EVGA that I used is clocked at 1202 MHz whereas the GTX 680 was at it’s default clock of 1006 MHz. Even with that said – then why doesn’t the 650 Ti beat the GTX 680 since it is clocked at 1071 MHz? The only data that makes sense from these tests are the results from Fluidmark. The cards improve in a linear fashion based on how they are positioned by NVIDIA. Interesting results…but overall I’m sticking with the 650 Ti in my system – as it is the best all-around performer: value, efficiency, and performance.

    seen a new XFX 240gt 512mb card on ebay for 25.99 would 240 be enough to run phys on high without seeing any performance issues

    ok cheers for reply struggling to find a decent card thats not that dear using along side 6990 so it wont have to be as powerful as 6990 will be doing rendering and nvidia card just doing the physx from what i understand, also some of the more powerful nvidia cards hinder the performance while running physx

    I'm still using a 9800GT for dedicated PhysX with a pair of OC'd 6950s in Xfire (so, pretty similar to a 6990). The 9800 seems to keep up just fine, though I haven't really done any empirical testing. I do have hardware monitors for all three cards running on a second screen, and I never really see the 9800 really maxed out. I'll pay a little more attention when I play tomorrow.

    I am on gaming at 1920 x 1200, but I'm not really sure how much resolution would matter for the PhysX card. It certainly isn't rendering those extra pixels. You might argue that there could be more PhysX affected objects in view with the wider FOV, but even nearby offscreen objects get calculated, so that point might be moot as well.

    The big hit would be the main GPUs having to render all of those little PhysX objects bouncing around, with the wider FOV there could be considerably more of them onscreen at once. In particular I'm thinking of those oil-well type machines that throw the rocks up into the air when they slam down.

    Ok so playing through the "Mine all Mine" level last night by myself in Tundra, there is a lot of flying rocks and debris in that area. I never saw the 9800GT go above 25% usage. I had the frame rate limited to 62 (1920x1200, max settings), and it was pretty solid there, I did see it drop down to 50 in a couple spots with a lot of rocks flying around, but no corresponding dips or spiks on the physx card at those times.

    These results felt pretty typical for this game (I've played through once before). I'd say that, at least for BL2, 112 cuda cores do the trick just fine.

    Again, though, I'm really not sure how Eyefinity and Physx mix. My hunch is that impact on the dedicated card won't be all that great.
