Generally speaking, more expensive hardware leads to better performance. Currently, the most famous computer companies include Intel, AMD, and Nvidia. Intel is known for their CPUs, while Nvidia is usually known for ther GPUs. AMD has a good reputation in both CPUs and GPUs.

Powerful hardware is usually associated with gamers. Modern games sometimes require high-end computers to run. Sometimes, good hardware is needed so that the game can run with good graphics and good speed. People usually use FPS (Frames Per Second) as a benchmark for computers. Computers that can run games at a higher FPS are more powerful and thus more desirable.

However, good hardware doesn't just benefit gamers. Programs you may need for work such as Unity, Adobe Premiere, OBS, or other software work best with good hardware. High quality hardware also tends to last longer, so it is also a better investment.
