I’m putting together a new PC build and plan to reuse my RTX 3080 GPU from my current setup. Eventually, once GPU prices stabilize, I might upgrade to a 5080 or 5090, so I picked a 1000W power supply with that in mind. Here’s what I have planned so far: an AMD Ryzen 7 9800X3D CPU, Thermalright Peerless Assassin 120 SE cooler, Gigabyte X870 EAGLE WIFI7 motherboard, 64GB of G.Skill Flare X5 DDR5-6000 memory at CL30, Samsung 990 EVO Plus 2TB PCIe 5.0 SSD, Phanteks XT Pro Silent case, and an EVGA SuperNOVA 1000 P5 80+ Platinum PSU. I also already have a Dell UltraSharp 34.1″ 3440×1440 monitor. Does everything here look compatible and wise, or is there anything I should reconsider?

One more thing about your RAM choice: avoid Crucial or any Micron-based chips if you want easier tweaking and better overclocking headroom. Those chips tend to be tougher to get stable at high speeds or low latency. Most good DDR5-6000 CL30 kits use Hynix memory chips, which are usually friendlier for performance tuning and generally more reliable for gaming and heavy multitasking. So look for kits that specify Hynix rather than Micron or others — that should save you some trouble down the road.
Heads up on that DDR5-6400 RAM you were considering — the Ryzen 7 9800X3D’s memory controller might not play nicely with those super-fast speeds at a 1:1 ratio. It might end up defaulting to a lower speed anyway, so you’d spend extra without much gain. I’d stick with DDR5-6000 CL30 kits to be safe; it’ll likely give you rock-solid stability and nearly the same performance.
Ah, thanks for letting me know! I’ll look for the 6000 MHz CL30 kits instead to avoid headaches.
If you’re open to some alternatives, I found a solid build that swaps a few parts for similar or better performance and improved features. For example, an MSI MAG B850 Tomahawk Max WIFI motherboard has that 2×2 USB-C header which you can use with a compatible case like the NZXT H5 Flow 2024. Also, consider an Inland Performance Plus PCIe 4.0 NVMe SSD; it’s great quality and often more affordable than PCIe 5.0 drives like the Samsung 990 EVO Plus. The PSU I’d recommend is the ADATA XPG Core Reactor II 1200W — 80+ Gold and loads of power headroom for future GPU upgrades. Finally, adding some efficient case fans can boost airflow without breaking the bank. This can keep the build cool and quiet without much extra cost.
I was a bit worried the B850 boards had issues supporting the 9800X3D smoothly, and I’ve had frustrating experiences with MSI motherboards before. But your points on USB-C and airflow are good ones to think about.

Good call! I’ve used Crucial for years but didn’t realize their Micron chips could be tricky. I’ll hunt for Hynix-based kits then, thanks for the heads-up.
