Gamer PC or desktop pick difference?

Hay I have in front of me to buy a new calculator now I see there are gamers PC and desktop PC What exactly is the difference between both? For my part I would like to play for a few games like Calculator GTA 4 or the Assassins Creed series, work on Word and watch Liquid series on Netflix and co.

In fact, gaming PCs usually have more graphics power necessary for gaming, but there are also some PC retailers who provide trashy old office PCs with a few colored LEDs and sell them as gaming PCs, even if the devices are unsuitable for it. Therefore, you can't always go after that.

Good traders are e.g. Dubaro or hardware advice.

As the name already shows, gamer PCs are geared to speed. Faster computing power, better graphics cards with more power and more graphics memory.
Depending on the budget, there are differences again. Rule of thumb, how more expensive the device the higher the game power.
Attention MAC computers are not suitable for gaming.

Word processing and watching movies is not a problem for any modern PC.

Desktop PCs are not designed specifically for the game.

A desktop PC can also be a gamer PC.
Desktop PC simply means that you have a computer where monitor, mouse and keyboard are connected, whose place is fixed according to the desk. Whereby it can be differentiated once again into a TowerPC.

The opposite would be the laptops.

The gaming PC is just a word to describe that this PC has more power to be suitable for games.
You can watch TV series and work on an office PC as well as on a gaming PC.
However, you should not use the office PC to gamble, especially on the newer parts of the Assassins Creed series.

PS: The term "gaming PC" is also often abused to sell bad hardware expensive. In some cases, the PCs are not worth calling it a gaming PC (although they are too good for an office PC).
