Will i see a lot of graphic differences between the xbox series s and xbox series x?

I don't play a lot, maybe 1-2 times a week is the xbox series s enough for me?

That won't take anything away. Of course, they have built different hardware among each other, but all in all you won't see any differences. And if it does, you will only see it if you put all the consoles next to each other and compare the images.

Series S:

Maximum 1440p at 120Hz
Xbox 360 and Xbox One games will run as they run on the Xbox One S.
No drive → don't buy or sell used games
Of the 521GB there are 364Gb free memory, whereby games are loaded onto the Series S with only 1440p textures and therefore require less space than on the Series X.

Series X:

Maximum 4K with 120HZ (and theoretically 8K with 60Hz)
Xbox 360 and Xbox One games will play as they would on Xbox One X.
Drive → Save money by selling used games and selling played games
From 1000Gb, 802GB are free, as the games are loaded onto the console with 4K textures, games are a bit larger here

Thank you. I wanted to hear that. Will it be on the market on 10 am or should I order it from Amazon? But it just says that she won't arrive until 12 …

I have no idea when the release is, but personally I would buy it where it is cheaper… A couple of days won't matter anyway… I also recently bought the xbox one, simply because I was too stingy and my computer actually everything packs without problems 🙃
