Is This Parts List Good for My First High-End Gaming PC Build?

I wouldn't go for the 5080; the 5070Ti is a way better deal right now. Plus, you might want to hold off on upgrading until the RTX6000 series drops. Rumor has it, the 6080 will come with 24GB of VRAM, and it sounds like the whole 6000 line is set to be a significant upgrade beyond what we've seen recently.

If you're planning to game at 1440p, this setup should last a good while! I usually prefer the 7800x3d over the 9800x3d due to a smaller performance difference with a significant price gap. But given your budget, the newer model might be a better long-term choice. Also, consider getting a more robust SSD for increased storage as games get bigger. It’s an easy upgrade too. And don't bother getting Windows Pro unless you actually need those specific features; save your money!

Your parts list looks solid! I recommend waiting a bit for memory prices to come down, unless you're okay with spending $400 on the RAM now. Additionally, think about getting a 1000w power supply for better stability. I personally don’t love the case you chose, but that’s just me. Also, consider your fan setup—make sure you'll have enough airflow and maybe grab some extra fans if needed. One last tip: I’d suggest getting braided cables since they’re easier to manage than the standard ones you get with the PSU. Good luck with your build!

Overall, I think your list is great, and you likely won’t need a bigger PSU unless you're planning upgrades in the next 8 years. To future-proof your build, I’d swap the AIO cooling for a high-quality air tower cooler. Also, instead of the 990pro, check out options like the FireCuda 530r—they're cheaper and have a better endurance rating, which is crucial for long-term use. The 5070ti might offer better value too. Just remember, you might need extra fans as well!

All those parts seem good! But how much does it mean to you to build your PC yourself? I ended up building mine, but I recently found a prebuilt one that's a lot cheaper with similar specs—about $1k less! Just a thought!
