Even with the advent of cloud-based streaming, there will always be the demand for the best gaming PC money can afford. For best-in-class fighting games like Dragon Ball FighterZ and online shooters that require a fast and fluid frame rate and zero latency, nothing compares to the experience of playing games natively using the components of your choice. 

Whether you prefer the sheer horsepower of an Nvidia graphics card or the value of AMD, the vast majority of PC makers give you the option these days. That being the case, there’s little difference between building your own computer and buying the best gaming PC straight off the shelf these days. Either way, you’re bound not to be disappointed by the end result.
