Believing in a single number – when shopping for a computer, there are several numbers that are mentioned and a few that are disregarded. For example, many computer shoppers believe that an i7 processor is better than an i5 and although it is, there are several high quality i5 chips that will knock the socks of their i7 counterparts.
So rather than simply focusing on high numbers, it is important to consider the components of the computer and other metrics such as clock speed, hyper threading and cache size. Not knowing what your operating system includes – there are several operating systems to choose from, each with their own set of pros and cons.
