I'm looking for a gaming laptop on which you can play simple games like Minecraft but with different mods. I want to spend 400 euro on this gaming laptop and I also want to use it for school purposes such as Word, Excel etc. (Please have a good laptop that lasts a long time and is good for 400 euro)
You don't get that for 400 euro. Even with a PC it gets difficult and laptops are even more expensive.
A dedicated graphics card is not included at 400 euro. So you are dependent on the integrated graphics unit of the CPU. Then you have the choice between AMD and Intel. At the price point, the two will not differ much.
With Intel, the processor should be at least an i3 and with AMD a Ryzen 3. The choice of available laptops is very limited. I found https://geizhals.de/...mp=2037667.
As I said, gaming is not really possible with them. If you still need a laptop for 400 euro, it might be advisable to look for used devices.
