I see so many threads talking about this bottlenecking that etc, when they are really just talking about somebodys weakest component

To me a bottleneck is:

A component that is significantly less advanced and improving that component would increase etc fps by a huge ammount,

ex
a 2ghz e2180 bottlenecks a gtx285

but a 3.5ghz e2180 does not bottleneck a gtx285

I may be completly worng feel free to post your opinions!

People throw around the word bottleneck too often.

A bottleneck is exactly that.

Think of a bottle with water in it. If you tip the bottle upside down, the rate at which the water will come out is limited by the diameter of the neck. Like water coming out of a bottle and going through the bottleneck, there are times when another component in a computer system will simply not be able to keep up with another, and will limit its potential.

Yeah a bottleneck is the slowest component. You are correct that people shouldn't use the term unless the component is seriously holding the system back. I wouldn't call a CPU that lags behind the GPU by 1fps a bottleneck, but technically it would be.

Bottlenecking is when you a super-fast component (e.g. ATI HD5870) which is the big end of the bottle, and a single core processor (the thin end of the bottle). The big end of the bottle can hold/process more information and send it because it's bigger. The thin end of the bottle has less room (power) so it can't keep up.

Sorry if that's confusing :s.

I don't know why you're putting unicore processors into the equation, whilst they can be a bottleneck, they're a rather bad example :|
