I found a used PC listed for €200 with a Ryzen 5 2600, RTX 2060, 16 GB of DDR4-3200 memory, and a 500 GB SSD. I'm considering replacing the processor with a Ryzen 5 3600 for about €45, bringing the total cost to roughly €245. Is this a good deal, and would it be suitable for playing CS2 at a minimum of 144 FPS? I'm also wondering whether upgrading later to a Ryzen 5 5600 or another newer CPU would cause compatibility or performance issues on a motherboard that isn't based on the B550 chipset.

€200 is a very good price if the parts work properly, though you should test the PC and check the condition before buying. Don’t assume it’s automatically a bargain without verifying that it boots, runs games, and has a reliable power supply.
It’s a solid budget gaming system for the money, but keep expectations realistic. The RTX 2060 and 16 GB of RAM are still usable, while the Ryzen 5 2600 may limit performance in CPU-heavy games. CS2 should be playable, but maintaining 144 FPS at all times will depend on resolution, settings, and the rest of the system.
I mainly want to play CS2, so I’m hoping it can stay around 144 FPS with competitive settings.
I wouldn’t rush to buy a Ryzen 5 3600 unless it’s extremely cheap and your current CPU is holding you back. A Ryzen 5 5600 would be a more worthwhile upgrade and pairs well with the RTX 2060. Check the motherboard’s CPU support list and update the BIOS if necessary; it does not need to be a B550 board. Older compatible boards can run a Ryzen 5 5600, although PCIe support may differ and usually won’t noticeably hurt an RTX 2060.
So the motherboard model and BIOS version are more important than whether it is B550, and the graphics card shouldn’t be seriously slowed down just because the board is older?

Exactly. The price is attractive, but checking the seller, hardware, temperatures, storage health, and power supply matters more than rushing into the purchase.
