How can i see if my cpu is bottlenecking my gpu?

So im pretty sure my 6800k is holding back my GTX 660 sc, but i want to make sure. Someone said its as easy as just opening Task Manager while youre gaming and if it shows the cpu is at 100% and the gpu is lower then the cpu is bottlenecking the gpu. So i tried it right now, but i just remembered there is nothing in TM showing you what your gpu load is. So i would like to know a good, free, easy to use program that shows my cpu and gpu load. What is a good program for that? Any help, recommendations, and advice is welcome. Thanks!

    Open Hardware Monitor. http://openhardwaremonitor.org/

    Is that the same as HWMonitor with the red icon? I already have CPU-Z which doesnt work for my goal, and HWMonitor which i dont like to use because it keeps working in the background unless you end them in Task Manager processes.

    No, it's a different program. It actually closes when you close the window; you don't need to end task it in task manager.

    Neither of them show the load of the cpu or gpu
  5. Open Hardware Monitor definitely shows CPU and GPU load. I use it all the time.

    Sorry, i was derping. Yeah it works great, but how am i supposed to see the percentages while i am playing?
  7. Unless you have multiple monitors, you can't really. However you can turn on plotting and have it plot CPU/GPU load. Then play your game and then exit/minimize it to look at the plot retrospectively.
  8. no
  9. How do I turn on that plotting thing you're talking about?
  10. View -> Show Plot.

    Then check the sensors that you want plotted.
  11. So i did the plot thing with Open Hardware Monitor and was playing Far Cry 3. Shows that all 4 cores were around 100% and the gpu was around 50%. Seems like a tiny bottleneck to me...
