Intel Q9450 vs Phenom 9850 - ATI HD3870 X2

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

Dude, your link proves his argument.... almost the whole document is discussing CPU and GPU bottlnecking....

What part do you not understand?

Yes that paper discuss CPU AND GPU bottlenecks. And how you decrease bottlenecks. But where do you see that that one bottleneck stands for 100% of the total time? If you have a video card running at 2000 GHz it will maybe render the picture in notime. Almost all time that needs to render the picture will be the processor time. But even if the GPU is extremely fast it will need to add a fraction of the total time.
If you have something that is slow you will of course look for areas that takes most time. But even if something takes very much time it doesn't use 100% of the time.
