If you are a gamer and have not invested in proper equipment, then you are missing out a lot. More than you can imagine.
Because without proper equipment, then how do you expect to have a decent performance? It is like expecting to win a Grand Prix without a proper car. It is not possible at all, and it does not matter how skilled you are, it does not really matter.
You Need It Badly:
You need a good chair badly, because otherwise, you will not be able to endure a long gaming session. And you do not need to spend a lot of money on it, because you can get this awesome inexpensive gaming chair.
For the mouse and keyboard, you need something that supports you in every game, not something that stops you. There is nothing worse than a bad mouse and keyboard, because they prevent you from releasing your full potential.
The Way Your Skills Manifest:
You need to look at your equipment as the medium by which your skills and talent can manifest into reality. They are the medium, and therefore, they need to be of the highest quality you can afford.
If you want to succeed on this, then you need to make a good investment in proper equipment, because that is what elite gamers do.
You can be very talented, sure, but if your equipment is not up to the level, then you will fail. That is why top level gamers invest into it, because it allows them to have a better performance. Simple and direct.
These two points are enough. As you can see, you need to invest in proper gaming equipment, because it is what you need to manifest your real talent.
