What exactly is bottleneck?
Last response: in CPUs
I've seen the term "bottleneck" on here quite a bit, but don't know exactly what it means.
I know it has something to do with the video card being so powerful it takes over the cpu and..makes it slower?
If someone could please clear this up that would be great
I am sorry for being a noob.

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.
The term bottleneck is taken from the 'assets are water' metaphor. As water is poured out of a bottle, the rate of outflow is limited by the width of the conduit of exit—that is, bottleneck.
By increasing the width of the bottleneck one can increase the rate at which the water flows out of the neck at different frequencies. Such limiting components of a system are sometimes referred to as bottleneck points.
So, if u have a latest top GPU, like HD 7970 and pair it with Intel Core 2 Duo E4500 - 2.20GHz CPU running with 2GB of RAM,
than u wasted load of $$$, because rest of the system is so slow, it will degrade the GPU power.
Not that anyone would buy this set up : )

It won't degrade the GPU, it just won't let it perform to its full potential.

Not exactly take over or make it slower. The video card remains very fast & will finish the its job & present the result to the cpu for further processing as quickly as it can. On other hand, the cpu will take the job & process the next step but does it slower such that the video card has to wait very long before it gets the next task... So as $hawn said, the video card can not reach its full potential because it has to & wait long for the slower cpu...
I think the term gets thrown around a little too loosely. Nowadays, if CPU X get 120 fps and CPU Y gets 115, CPU Y is lauded as a horrible bottleneck and a worthless piece of crap worthy only of being a paperweight.
To me, a bottleneck is something that will choke off a significant amount of performance. Something like a 2.2 GHz dual core running a pair of GTX580's would be a bottleneck as youd be losing probably a third of your potential frames per second.
I think its all relative to what youre using. If youre running an Athlon II X3 on a single 6870, then yeah a 3570K would give you a few more frames but it wouldnt be enough that youd notice in actual game play. However, those same two procs powering a pair of GTX670's and youre talking a pretty big difference and that would be a true bottleneck to me.![;)]( ";)")
