Needing a basic computer for specific games

I finally got enough money to get a desktop but I can't seem to find ones that don't have a 4090 or a basic ass video card.

Need like a mid-level that is amazing for cpu games and ok for video as I don't care about visuals

Basically a computer that can run heavily modded Factorio, Minecraft and rimworld.

Anybody have any links or options that are under 800?
