GTX 680 performance problem and now GTX 690

Hi people, i basically had major performance problems with my 2x GTX 680 sli which i purchased from Amazon last week,

http://www.tomshardware.co.uk/forum/377000-15-performance-problem

i thought it might be the cards, so i ordered a Asus GTX 690, which was delivered today but guess what i now have the same problem with this card, and i have done a fresh install using a brand new HDD with Vista Ultimate 64bit.

If anyone can help i will be most grateful.

  1. sorry here are my pc specs:

    Thermaltake Armor +
    Antec HCG 900w
    Asus Rampage Extreme III
    Corsair Dominator GT @2000mhz
    Intel i7 960@ 3.2ghz
    2 x WD Black Caviar 1TB RAID 0
    Asus GTX 690
    Asus VG236H 3D monitor
  2. i assume you have installed the drivers for them?
  3. yes, from the nvidia website and tried also from the cd
  4. SLI doesn't work for every game. I see that you are using a 3D monitor too, that kills performance big time. That could be your issue.
  5. i have tried 6 different games, and i have disable 3d vision, the performance is roughly the same ias i was getting with my old gtx 590
  6. after reading through that post my only question is have you tried overclocking your cpu? if not why not? that cpu is 3 generations old. thats a lot.
  7. Try overclocking your CPU and see if you see any performance increase, it could very likely be your CPU that is keeping your FPS down.
  8. I would say you probably have a CPU bottleneck, try OCing some and see if your GPU is utilized more.
  9. I strongly suggest you overclock your CPU to 4.0Ghz, a decent cooler like the NH-D14 or the new H100i should be sufficient. Not all games utilize multi gpu configurations, but when they do you should be able to max out settings and still have above 80+ fps. BF3 for example @ 1080p should be hitting 90+ fps most of the time on your system again your CPU may be the hindrance. What are the GPU usages during gameplay?

    in bf3 his cpu is definitely holding him back. an overclock would help a lot.
  11. In bf3 with my old gtx 590 I was getting around 80-90 fps, I have just overclocked my CPU to 4.0 and if anything it only gave me only an extra 5-8 frames. If I purchased the rampage extreme iv and a 2011 extreme CPU will it be ok then, would I notice much of a difference.
  12. what are the specify fps you are trying to get with 3d enabled? Why bother with higher than 80 fps?

    just take a step back and stop trying to throw money at this problem. no buying the most expensive cpu and motherboard you can get will not solve the problem any more then a 3770k cpu and 125 dollar motherboard. it sounds like to me that you are getting to your cpus limit of how much it can output.

    try this. lower your graphics settings in bf3 to low and note the fps. if they are not much higher then your cpu is holding you back.
  14. ^+1
  15. your running WINDOWS VISTA!. Get a copy of windows 7/8 now! +1 to the cpu bottleneck thing. you said OC'ing cpu gave more fps, so also there must be some sort of cpu bottleneck.
  16. Yes but it must be more than the CPU, on benchmarks on other websites they are showing double if not triple the fps than what I am getting.

    your fps seem like where they are supposed to be in bf3.
  18. You got Windows VISTA??? Are you nuts? It's probably the worst gaming software right after that apple stuff. It lowers the performance of your hardware so much, you can't even imagine! :pt1cable:
