going back to that message. When some here say that the CPU bottlenecks the GPU. Is this what they mean.

+ = processor is working
- = video card is working

Slow processor
+++-----+++-----+++-----+++-----+++-----
Fast processor
-------------------------
Do you mean that if the processor is fast, then time spent by the processor isn't a factor. The only time that counts is the gpu

Or if you say that the video card is bottlenecked by the processor is it like this then?
++++++++++++++++++++++++++++++++++++++++++++++++

What I have read is that cpu will always bottlneck the videocard and the videocard will always bottleneck the cpu. What is a bottleneck? If something use 5% of total time, is this a bottleneck? What we are arguing about is maybe when something is a bottleneck or I don't understand. It isn't possible to remove time completely from the processor or the video card
your correct thers always a bottleneck, but you dont want to have a cpu bottleneck. Gamers want the reach the gpu bottelneck to get the maximum out of there rig.

Also your graphs are kinda bad to show either cpu or gpu bottleneck, you cant only examine the cpu or the gpu, you have to watch both:

working: +
idle: -

GPU bottleneck:
GPU ++++++++++++++++++++++++++++++++++++++
CPU --+--+---+----+-----+----+----+----++-----+++-

CPU bottleneck
GPU --+--+---+----+-----+----+----+----++-----+++-
CPU ++++++++++++++++++++++++++++++++++++++

both are extreme cases, but with nowadays graphics cards you reach the CPU limit far more often then the GPU limit, meaning that potential of your graphics card is unused.
