DrewWhen other components are being limited by it. If he upgrades his GPU and if there are any FPS gains at all (especially with GPU intensive applications), I can assume there is no bottleneck with CPU<->GPU.
jp_What do you think a CPU bottleneck is?
DamnKetoso, maybe it's only a cpu bottlenecking problem.I don't think so. The CPU is just slow.
I forget what review site had a nice experiment about bottlenecking. But basically they benched a high-end intel cpu with a configuration of regular/tri/quad-SLI nvidia graphics cards and the benchmark showed a clear bottleneck which was indicated with near zero fps gains between the SLI configurations.
Though I still have a tough time getting my mind around this concept of 'bottleneck'...How can you even diagnose one without having to upgrade/spend money. Most of the times I see it used, it's just a moniker for "slow cpu".
A bottleneck in a computer is anything limiting your performance. That is why unless your computer is infinitely powerful, you will always have a bottleneck. So in this case, since TF2 is very CPU dependent, his slow CPU is the limiting factor or bottleneck.
Unless you have some obscene or cryptic problems with your computer you can easily determine what kind of bottlenecks your computer has with certain applications without spending any money.
