Over the years the components in laptop computers have evolved with impressive results. This is evident in many used laptops under 100 and each one basically represents a different point in the overall evolution.
Without getting overly technical it seems like the best match of processor is with the hardware design which it originally came with. This is often the case with any product but when it comes to computers there are actually several other points which make this even more interesting.
Many computers give the user the ability to do an upgrade as they see fit. This is not only handy but it allows for a never ending level of opportunity for the owner of the used laptop to make their computer just the way they want it. This applies to both hardware as well as software in the used laptops.
