I get tired of seeing the term bottleneck as i know you do as well, a bottleneck can be viewed from 2 different perspectives, the CPU could be bottleneck'n the GPU or vice versa, the GPU could be bottleneck'n the CPU, but what if the CPU is already maxed out and the GPU is 1 size or more too (powerful), i hope you would not call that a bottleneck as the CPU cannot be increased to match the processing power of the GPU, instead that would be a simple case of overkill on the part of the GPU, my question is would a GPU that is considered overkill be considered a benefit or detriment to the CPU, am sure the distinction to be made lies somewhere between the benchmark we are basing against, is the program in question CPU or GPU intensive, are we viewing the problem from the CPU's POV or the GPU's POV, it's a complicated question i know..
 
Solution
Buying an overkill GPU, as you put it, is more of a waste of money than anything else. It isn't going to hurt anything, but the GPU isn't going to realize its full potential waiting on a CPU that cannot keep up. The only way I wouldn't consider it a waste of money is if it was a deal where you were buying the overkill GPU now, to replace a very poor GPU, as part of an upgrade path to a new system.

Solution

That is the answer i was looking for, 'It isn't going to hurt anything'..
So it won't decrease performance by using a GPU that runs faster than the CPU but it won't increase performance either, unless the program currently running can take advantage of the (extra) graphics processing power..

 




Right.
