Which gaming pc is better of the 3?

For fortnite

The first PC is the best. But the other two are marginal only worse, which of the three PCs you take now you will not notice. However, you can better overclock the hardware advice, thanks to the small cooler!

Almost all are the same. The main difference lies in the motherboard. That's just slightly different for one. Check out the board's specifications to see if they offer what you want.

In terms of performance, everyone is equally strong.

But the first one has a bit more trivialities on offer than an extra Cpu cooler and preinstalled Windows 10.
