Which processor?

I only play Minecraft and have heard that the game is more processor-heavy.

Should I now take a Ryzen 5 1600 AF and a better GPU or the Ryzen 5 3600 and a worse GPU.

My question is which GPU would you use for which processor?

Rx 5500xt for the ryzen 5 1600 af and an rx 570/580 for the ryzen 5 3600

What's your budjet Would go for Minecraft with Intel and Nvidia

So 500 euro

Then I would take the Ryzen 5 3600 and an RX 570/580

Since you can rather assemble something used like I7-6700k and GTX 1060 6gb then 16 GB DDR4 and 600 W power supply

At 500 euro nvidia / Intel makes no sense because amd is worth it

I mean also used because for 500 (new) nothing reasonable wars

The graphics card can still be upgraded later, the main thing is that you have a good processor that delivers enough power.

Well an rx590 and a ryzen 5 2600 are quite sufficient for minecraft

Neither of these. You can use a much weaker system for Minecraft. I don't even know how you want to put together a system with RX 580 8GB and R5 3600, provided that 500 euro is the budget for a complete system and not just processor and graphics card.

But both the I7 and the 1060 are better because they only want one RX570

The system should last longer, I don't want to upgrade right away

You also need storage.

If the system is to last a long time, the CPU is most important, so I would take the 3600.

I've already

OK.

If you only play Minecraft and don't plan anything else, I would rather take a 1600AF with a cheap board and RX 570 8GB, 8GB 3200MHz RAM, cheap case and cheap power supply (as already in your configuration).

But I have enough money for a better system, why should I take the worse GPU and CPU?

Because you don't need a better system if you only play Minecraft.
