GTX580 running worse than my HD6750 - why?

Hello guys! I have a small problem: I replaced my ATI Radeon HD6750 with an ASUS GTX580. So things should run a little bit better, i guess. But they don't. GTX580 gives worse performance than my old card. My hardware is working fine, so I guess, there's a software problem - any ideas? Here's my system:

CPU: QuadCore AMD Phenom II X4 Black Edition 955, 3215 MHz (16 x 201)
Mainboard: Gigabyte GA-890FXA-UD5 v2
RAM: 2x G Skill F3-10666CL8-2GBECO 2 GB DDR3-1333 DDR3
GPU: NVIDIA GeForce GTX 580 (1572544 KB)
PSU: Seasonic X-560

I also had the thought, that the GTX580 drains much more power and needs more than my old PSU. Any hints?

  1. I would suggest fresh install of nvidia most up to dated drivers. But you probably have done that already. Check temps under load, and make sure gpu works on full speed under load. You may have a faulty gpu.
  2. GPU works fine in another PC. Drivers are up-to-date. Normal temperature is around 42 °C. I will test it later in a game with GPU-Z sensor log.
  3. Technically speaking, your PSU falls below the minimum system power requirement which is 600 watts (source: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-580/specifications). Can you try a larger power supply (at least 600-650 watts, maybe borrow one from a friend)?
  4. I will try to get a larger PSU, see if it changes anything. Got no BSOD's, maybe a random pc power down once this month - indicator for PSU? I'm running BF3 on maximum settings - it ran on Metro with 40 fps (on RADEON), now it's around 30fps, sometimes even less. Diablo 3 also stutters -_-...
  5. If I were you, I'd reinstall windows. Since you had an AMD card, your computer has AMD driver remnants, which plague the performance of the nvidia card. Reinstalling windows would get rid of them and would warrant your games are at full performance with the incredible GTX 580 :).
  6. before you do any hardware replacment is your mb bios up todate..sometime vendor put in patches for cpu..ram and gpu into there bios.
  7. While you should be able to just remove AMD card and plug in Nvidia card, it sounds like that didn't happen this time. Grab a driver cleaner program and try again. Bios update would be my next step seeing as GPU worked in other system. PSU should be fine unless its dying.
  8. Driver cleaner isn't an option, because i already formatted C and re-installed Win7. So, no old drivers should be left on the disk. I'll see if i can get a bios update for my board :D Thx.
  9. PS: My mainboard bios update only patches quiet n cool compatibility, new JM363 support and new RAID ROM support. That doesn't help me with my GPU, or?

    that is a most excellent PSU
    Reviews - Seasonic X-560 560W
    80 PLUS® GOLD Certified
    As was the case with the other X series units, this puppy uses the VRM approach for the minor rails. That's how come Seasonic can get away with that big 552W 12V rail on a unit rated at 560W total power.

    i am jelly . . :lol:
  11. Unless your PSU is faulty, that seasonic is plenty for the 580. The recommended wattage from the video card manufacturer is a guesstimate on the minimum wattage a terribly designed PSU could have and still be adequate for the card. Your seasonic is awell designed PSU, it's 46a +12v rail supports the 580 without even breaking a sweat.

    I notice that two of your pci-e slots have a ceiling of 8 lanes and 4 lanes respectively, regardless of using a single card. the 580 wouldn't happened to have been plugged into the 4 lane slot, would it?

    The 580 will be bottlenecked with the Phenom, but not enough to warrant worse performance than your previous card.

    you'll need to overclock your 955 to 3.8ghz at least
  13. GeForce GTX 580

    On your average system the card requires you to have a 650 Watt power supply

  14. much to learn young jedi does. . . .

    Subjective obtained GPU power consumption = ~ 280 Watts

    280/12= 24 amps needed for the card. forget the total wattage of the PSU. a less than quality PSU would need to be 650 watts for a 25+ amp 12 volt rail.

    OP's PSU has 46 amps. that is what is important!

    Just to add to looniam's schooling...

    For a gaming system, the strength of the 12v rail is more important than the PSU's total wattage.

    Hm - the GPU is plugged in on the first slot besides the CPU - in my opinion that should be the normal slot, or?

    No..., really?! 3.8 sounds fishy XD.

    But thx for all the support up to now guys !
  17. Your NVidia card has additional features, such as advanced PhysX support. Sometimes a "max" preset with an AMD card is not the same as a "max" preset with an NVidia card due to settings being tweaked for a specific architecture. I though my GTX570 wasn't up to par with my HD6950, until I realised it was also rendering every spec of dust and debris in Metro2033. Just a thought.

    Also, the last I read, the AMD cards do better with underpowered CPUs as compared to Nvidia cards.
  18. @tjs4ever: (I hope I understood your point lol). I know that the card is much better and I know that my system would propably run "more compatible" with an ATI card. But isn't there a way to get the GTX running at least as smooth as like my old one? Without changing any more parts? I mean - I most certainly "could" buy a new CPU, but.... hm...

    So basically, that's was all you guys are saying?!: Get a new CPU?

    :non: Phenom IIx4 955 need not be overclocked to 3.8ghz........i am running a gtx 670 with my phenom IIx4 955 BE on stock and IT DOES NOT BOTTLENECK MY CARD
    and i guess gtx 670 is more powerful than the gtx 580,isn't it?
  20. No, I fear I worded that poorly...

    I wouldn't be surprised that, upon deep investigation, your GTX580 was getting lower frame rates because it is actually doing more work: physX is an NVidia only technology, it makes things life like, it kills fps. Maybe tessellation is turned higher by default for that card? Maybe different or higher antialiasing. My only real world example is how my GTX570 got lower frames than my hd6950 in Metro2033: what I didn't notice at first is that some options were greyed out when using hd6950 (such as the physx settings) my GTX got fewer frames per second, but it was also rendering a hell of a lot more particles, and such.

    Best example I could think of: please don't change your hardware on my account.

    I can guarentee in the majority of games your 670 is performing on par or less to my single GTX 480 due to your CPU.
    We had pothead here before with a 3.8ghz 965 BE and could only just beat a single 480 in unigene tropics with 6950 crossfire...
    He went to a 2500k and now leaves that single 480 in the dust.


    i guess you are saying that your gtx 480 gives you around 70 fps in BF3 on ultra and 4xAA :heink: ? cause mine gives around 70 fps......
  22. Quote:
    10 fps slower than you...


    http://www.tomshardware.com/reviews/geforce-gtx-670-review,3200-5.html

    same results as mine so NO BOTTLENECKING
  23. The rig they used in benchmarking is way higher than mine but still the same results.....so i guess no bottlenecking
  24. ^^Guess we have to start a thread for that :P

    it would benefit from overclocking (with a 7970)
    Overclocking Benchmarks

    Thankyou looniam, i tried bringing my own results in to compare with an even slower card :)

    Nice bass :D

    i go to sleep listening to that as i count benchmarks in my head. :lol:
  28. Ok.....I thought it wasn't a bottleneck due to the same results as tomshardware....btw I am loving my purchase but my phenom is really old and I had already ordered the i5 3750k.......so was just playing around with both of them......
