What’s the best way to upgrade my gaming PC?

Some suggestions: consider a GPU upgrade, maybe a 5060 or something beefier like a 6700 or 4060 Ti. You should also upgrade your PSU to at least 550W. If you're low on storage, think about replacing your SATA drive and HDD with a larger SSD for speed. More case fans and a new air cooler like the Phantom Spirit should also help with cooling.

I’d recommend switching from 4 RAM sticks to 2, as this can improve performance. Also, it’s crucial to know what resolution you're gaming at since that will affect your upgrade decisions. New coolers will definitely help mitigate the noise and heat issues.

To tackle the heat and noise, I’d suggest upgrading your CPU cooler. A Thermalright Phantom Spirit is a solid, budget-friendly choice that should help. If you're looking to play at higher graphics settings with better frame rates, your GPU is likely holding you back. Think about upgrading it based on your budget and local availability. Just keep in mind that a new GPU may also necessitate a stronger power supply since 450W isn't enough for most mid-range cards.

If you're aiming for higher fidelity graphics, it’s definitely your GPU that needs an upgrade. Your CPU could also be a bottleneck in Cyberpunk if you're hitting those high FPS targets, but for now, it's better to focus on the GPU. Upgrading to an efficient cooler like the ID-Cooling Frozn A620 Pro SE or the Thermalright Phantom Spirit 120 SE can also help with the heat.

Honestly, you might want to consider selling your current setup and getting a new one instead. For effective upgrades, you’ll need 16GB RAM, a better CPU (like the 5700X3D), and definitely a stronger GPU. All these changes can really elevate your gaming experience.
