Will a high end graphics card decrease cpu usage ?

hi, does anyone know if having a highend gpu with a fx 8350 would you use less cpu than lower end gpu for example on bf3 im getting great fps anywaye from 60-30 fps with my fx 8350 and my 7770 gpu but it can go from 45% cpu to 55% of the entire cpu that doesnt seem right. would it use less cpu if I put in like a 7870 or something like that?

  1. Its probably because that FX has 8 threads and your 7770 is holding it back.
    What setting's and resolution are you playing at?
  2. Best answer
    The CPU and graphic card handles separate processes for games so the answer is no.

    If the GPU is too slow, then that means while you GPU is still trying to process graphic effects and texture placements, the CPU will be waiting for it so that it can continue.

    If the CPU is too weak, then the graphic card waits for the CPU to do it's thing like physics, NPC AI logic, collision, environmental perspective, etc. Then the graphic card can do the things it needs to do.
  3. im only playing at 1600x900 I know that bf3 is highlly multithreaded but I just woulden't think it would take up that much.

    I thought it would take up more, your playing at a pretty low res so more work is offloaded to cpu rather than gpu but only 55% usage seems about right, so why are you concerned with the usage? are you wanting to run other task's in the Background or something?
  5. Your graphics card is failing you, bottlenecking your CPU big time.

    IF you had a better graphics card, chances are you would be using more CPU too.

    Because then the graphics card wouldn't be limiting your CPU

    I think your cpu usage will go up with a stronger graphics card.
    The reasoning is that because the graphics card is less of a bottleneck, the cpu is free to gernerate more frames per second.

    The FX series are not known to be good gamers because of their relatively poor efficiency in instructions per clock.
    8 cores do not help much because few games use more than 2-3 cores.

    With BF3, it matters if you are single player, or multiplayer.

    In single player, BF3 is more graphics dependent, and your cpu should be fine.
    In multiplayer, the cpu becomes very important. Because of the difficulty of benchmarking multiplayer, there is not a lot of solid evidence on how 8 cores vs. faster cores behave.

    To help clarify your options, run these two tests:

    a) Run your games, but lower your resolution and eye candy.
    If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
    If your FPS stays the same, you are likely cpu limited.

    b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 50%.
    This will simulate what a lack of cpu power will do.


    Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
    set to 50% and see how you do.


    If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

    It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.
  7. yeas I know all about the fx chips i wanted this for rendering video, gaming and I woanted it to be more future proof than a four core I came from a Athlon 7550.

    I know a cpu change is a moot point.

    But, if you are asking if you could make good use of a stronger graphics card, do some testing with lower resolutions or eye candy so the graphics card will be less of a limiter, and see how you do.
    A stronger graphics card will always do better.
    Either in higher average fps, higher minimum fps, or the ability to use more detail.

    It is just a matter of how much better, and is it worth the difference you spend on it.
  9. well im hoping I can buy another 7770 and put it in crossfire almost every game ive played it plays at 60 fps almost all the time.

    Then why would you consider crossfire?
    You might win some benchmarks, but gameplay will be hardly affected. Many games and monitors are limited to 60fps.
    And... you may discover microstuttering. Read more here:
