Your system as configured is basically an office computer.

• What are the intended upgrades for?
• Are you trying to make a gaming system from it?
• Why did you buy the Noctua cooler?
• Why do you need a 3900x?
• What is your budget for upgrades?

Yes, Gaming on at least 1080p (limited by monitor). I want to update it a bit 2400G was making me trouble from the beginning... it is still making BSOD etc. Noctua I got for free, to be honest, I just need to buy a mounting kit for AM4. Budget not exceeding 800 GBP.
