In a chain of works to get the work done all that takes time in that chain is something that will add to total time. If you have a slow processor you may gain most to change the processor. If you have a slow video card you main more to change the video card. Hopefully the developers has optimized the game. This talk about my processor bottlenecks my video card or the video card bottlenecks the cpu I do not understand. They both participate in the work to render the frame. They both use time to render the frame. Buying faster video card or faster processor will decrease the total time. But both will still use up time that is added to total time to render the frame.

Here is a good paper: http://ati.amd.com/developer/gdc/PerformanceTuning.pdf
