What he is saying is that a 20% performance for JUST the CPU does not make the whole PC performance 20% better.
A 20% better CPU may only equate to a 5% overall PC performance improvement, which most people would not notice anyway.
And in fact most people who are using the internet would not notice any improvement at all, as it is usually the broadband download speed that is the bottleneck, not the CPU speed.
Exactly what I meant, thanks for clearing it up
Most day to day tasks are not bottlenecked by the CPU - hard drive speed is another major bottleneck. Only tasks which perform lots of calculations on data which fits in memory - such as video encoding, photo processing etc - are significantly faster of fast cpu's, and for most purposes its better to get a balanced set of all components that spend loads on the latest-and-greatest CPUs (which give far less performance per £). For games the GPU is still the key factor - a setup with a Radeon 4850 and 2.2GHz AMD CPU will run better in games than a Radeon 4650 and 3.2GHz Intel CPU.... The same game would run a bit faster given a 4850/Intel CPU pairing, but the bigger difference comes from the GPU, not CPU.
