I bought a used PC for $250 as an inexpensive starting point and would like to improve it for more demanding games. It currently has an RX 580 8GB, 16GB of DDR4 memory, a 1TB SSD, and an Intel Core i5-6500 running at 3.2GHz. Which component should I upgrade first, and what upgrades make sense without spending more than the system is worth?

The RX 580 is the oldest and most limiting part for gaming, so I’d start with the graphics card. A used GTX 1660 Super or RTX 2060 would be a noticeable step up, assuming your power supply and case can support it. The i5-6500 may still be adequate for some games, but newer titles could expose its four-core limit.
The exact CPU matters here, and the i5-6500 is an older platform. You can potentially find an i7-6700 or i7-6700K as a drop-in upgrade, but only if one is very cheap. Otherwise, a meaningful CPU upgrade would require replacing the motherboard and processor, and possibly the memory too. Since you paid $250, it makes sense to use it as-is for now and save toward a larger platform upgrade rather than investing heavily in it.

I only paid $250, so I’m fine with using it as a temporary system until I can afford a full upgrade.
