Bottleneck is when a piece of your hardware drags the rest down because it can't keep up with them. Usually when someone is talking about bottleneck on a pc is ether talking about the CPU or the GPU. For example if u have a very fast CPU and a not so fast GPU then the GPU is your bottleneck because the CPU could give u more performance but you can not get it because of the GPU dragging you back.

Copy/Paste from wikipedia:
A bottleneck is a phenomenon where the performance or capacity of an entire system is limited by a single or limited number of components or resources

For your system i am afraid that your CPU will be the bottleneck if you decide to upgrade to a GTX 650.

if your CPU bottleneck you will not lose any proformace but you will war money because your CPU won't let the GPU run at its full potential

You won't get as much performance as you should. Nothing "bad" will happen, except the fact that you waste performance. With the GTX 650 if u could get at least a dual core cpu it would be a lot better.

A bottleneck is a limiting factor.
Your current bottleneck for gaming is likely your graphics card now.
Once your graphics card is upgraded, your cpu may well become the limiting factor.

To help clarify your options, run these two tests:

a) Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, in windows power management, limit the maximum cpu% to something like 50%.
This will simulate what a lack of cpu power will do.


Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
set to 50% and see how you do.


If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.

yes if you upgrade you will get more the what you are at now. i would only upgrade the GPU if you plan to upgrade the CPU soon

So he will be loosing performance.

Lets say that with your current CPU and the GTX 650 at a game you have 30 fps, if u had a different much better CPU and the GTX 650 at that same game your fps could be 45 or 50 or 60.

So by having the CPU you have and getting the GTX 650 instead of having that 45 or 50 fps you will have 30 fps, that's what i mean loosing performance. You loose the 15-20 fps that you could have with a better CPU and the GTX 650.

no the GTX 650 will run better than his current GPU but you wast some of the proformace

lets say that you have his build right now and you get 30 FPS if you upgrade the GPU than you will get 35 - 40 FPS
if you upgrade the CPU and the GPU then you will get 60 FPS
so if he upgrade the GPU he will gain profomace just not all the proformace he could get if he upgrade the CPU

We are saying the exact same thing, with different words.

@MaxorCF
Bottleneck has nothing to do with unstable or "unsmooth" FPS. There is always a bottleneck in a system. The thing is that the bottleneck should not be big.
