Upgrade a PC, graphics card or CPU?

I want to upgrade my PC, because mine is pretty bad at the moment (Current CPU: Intel (R) core (TM) i5 2320 CPU

Current graphics card: Intel (R) HD Graphics 1.7GB)

I had before me to get a new graphics card, namely the MSI V341-236R Radeon RX 570 Armor 8G OC graphics card, cost 165 euro, but I noticed that my processor is also very bad, and now I do not know what to upgrade.

My budget is 200 euro.

I use the PC mainly for gaming (games like Fortnite etc.)

What should I upgrade to the PC to get the most frames?

Well, until now you do not even have a graphics card, but only the graphics chip on the CPU. So a dedicated Standalone GPU will bring a Monster Boost.

You can forget gaming without a graphics card. However, the CPU is also outdated as you said before. But there's no APU to play.

I would say: First graphics card → Then CPU

Actually, you would have to upgrade everything (ie processor, motherboard, memory and graphics card). If necessary, also the power supply, if this should be too old and / or too weak. But you can now buy the graphics card and then save on the rest. That would not go out at just 200 euro anyway. For this you would then have to go (including power supply) at least 350 euro.

Better to save your money and yes with a rx570 you are not completely wrong but makes no sense with this CPU because it is very lame. As CPU a Ryzen 2600 16gb ram and a b450 board soon take and possibly new power supply to enjoy the maximum performance of the 570th An Intelcpu I can't recommend you, there are some of Intel in this price range but these CPUs You can enter the bin again in one year at the latest.
