Will This PC Build Work for Unreal Engine 5?

Your build looks decent overall! However, I'd recommend upgrading that cooler for the 12700K, as it can run pretty hot. A better cooler, like the Phantom Spirit, would definitely help. Also, steer clear of the Xilence power supply; they're rated poorly. You could opt for something like the Rosewill VSB instead, which provides better reliability without breaking the bank.

I made some modifications to your build. Consider switching to DDR5 and an AM5 motherboard for better future-proofing. If your budget allows for a 9060 XT 16GB, it’ll significantly boost your frame rates.

Here’s a reworked list I put together:
- **CPU:** AMD Ryzen 5 9600X 3.9 GHz 6-Core
- **Cooler:** Thermalright Peerless Assassin 120 SE
- **Motherboard:** Gigabyte B650M GAMING PLUS WIFI
- **Memory:** Acer Predator Pallas II 32 GB (2 x 16 GB) DDR5-6000
- **Storage:** Biwin Black Opal NV7400 1 TB
- **Video Card:** Intel Limited Edition Arc B580 12 GB
- **Case:** Cooler Master TD300 Mesh
- **Power Supply:** ADATA XPG Core Reactor II VE 650 W

Total: around €1289. That should give you a solid performance boost!

If you're sticking with 32GB of RAM, it’s more effective to use 2x16GB sticks rather than just one 32GB stick. This way, you can take advantage of dual-channel performance. If you do want to scale up later, just grab another 32GB stick that matches your current one.
