A quote from the article:
Our guidelines for the Entry-level PC category are as follows. The entire computer system, excluding OS, should not exceed £420. Its primary, but not only, function is to provide a smooth and enjoyable online experience. This means that the cheapest processors won't be enough, as modern web pages and internet applications do demand some processing power.Entry-level PC - November 2014 @ Hardware.Info
Additionally, the system has to be able to efficiently perform internet-related tasks. This includes basic photo editing (cropping and resizing to upload or send a photo) and extracting compressed files. At the same time the necessary background programmes need to be active, such as a virus scanner, a firewall, and anti-spyware software. The computer also needs to be able to efficiently run word processing software and administrative programmes.
The cheapest PCs that you can currently buy are good enough for internet use. If you want to do other things, however, then you will quickly notice the limitations of the CPU and graphics processor. More powerful pre-assembled computers often turn out to have one weak component that becomes a bottleneck. Maybe it has a very fast processor, but lacks enough RAM, hard disk space, or a good enough graphics card.
