Today the Net offers a lot of reviews on hardware with performance tests and short conclusions. Unfortunately, not all hardware sites are able to follow prices on-the-fly. And a user is to decide himself what ratio is better "price/performance" or "price/quality".

In my opinion such approach suits only printers or scanners, i.e. those peripherals that can be considered as a separate device. The CPU is a heart of the system, its performance greatly influences the performance of the whole computer. Therefore, the "price/performance" is a complicated issue. Besides, you have to use several configuration systems for an objective estimation.
