Help me recyle my PC

Hey everyone,

I’m looking to recycle my old PC to improve my workflow and also make it ready for gaming. Right now, I use my PS5 for gaming, but when GTA 6 comes out, I want to be able to play it on my PC.

At the moment, I don’t need a new GPU, but I do plan to upgrade it in the future. For now, I want to reuse the following components:

  • My current GPU Gigabyte geforce rtx 2070
  • My CPU AMD Ryzen 7 1800x Eight-Core Processor.
  • 1TB Samsung 990 Pro SSD (with heatsink)
  • Two Noctua 120mm fans

What I need:

  • A good gaming MOBO
  • RAM (suggestions on speed & capacity are welcome) is DDR5 the best?
  • Possibly a new CPU if mine is too outdated (not sure what’s best)
  • A nice airflow case with not to much RGB

I’m not a PC expert, so I’d appreciate recommendations that balance performance and price. My budget is around €500, but I can stretch it to €750 if necessary or more if the upgrade is really worth it.

Thanks in advance for your help!
