First Time Building a PC – Need Your Thoughts on My Parts

Don't forget to add a hard drive for extra storage, even a 2TB one is super affordable for games you don't play often or for storing photos and recordings. But make sure to choose your GPU wisely; matching an entry-level GPU with that powerful CPU won't let you maximize performance.

I'd recommend upgrading your RAM to 6000MHz with a CL30 latency for better performance, and don't skimp on your power supply—an 850W Gold-rated PSU would give you more headroom for future upgrades. Also, make sure your motherboard supports BIOS flashback for future updates. The GPU might hold back your high-end CPU a bit, so consider a better option if your budget allows.

Assuming you're building for gaming, I'd increase your PSU to 850W and think about getting a larger SSD—at least 2TB. Modern games take up a lot more space than before!

You're looking at some significant bottlenecking here—a high-end CPU with an entry-level GPU just won’t cut it for optimal performance. I recommend using pcpartpicker.com to help organize your build. For CPU, the 7800X3D is cheaper and provides similar performance for gaming at 1440p. I'd also suggest air cooling for better reliability. Lastly, a 2TB SSD is becoming the minimum for gaming needs.

You might want to consider going with a cheaper CPU and then invest in better RAM, a power supply, and a more powerful GPU instead. It could give you a better overall balance.
