I'm planning a CHF 2,000–3,000 PC mainly for simple work such as LaTeX and Microsoft Office, with occasional gaming. About 80% of my gaming would be League of Legends, 10% Age of Empires II: Definitive Edition, 4% Cities: Skylines II, 4% The Sims, and 2% other games. I already own an LG 40-inch 5120×2160 72 Hz monitor, so I'd like to reach roughly 72 FPS where practical. AAA games are mostly covered by a PS5 Pro.
The current build uses a Ryzen 7 7800X3D, Radeon RX 9070 16 GB, 32 GB DDR5-6000 CL30, a 2 TB NVMe SSD, an 850 W power supply, and an Asus X870E motherboard with integrated 10 GbE. I also selected a Noctua NH-U12A cooler and several Noctua case fans because reliability, low noise, and straightforward installation matter to me. The Fractal North's appearance is also important.
Will the 7800X3D and RX 9070 be enough for these games at 5120×2160 and 72 FPS, or would an RX 9070 XT provide a worthwhile improvement? Which graphics card models are reliable and quiet? Are the Noctua cooler and fans justified, and is there anything else I should change or watch out for, such as cooler clearance, motherboard choice, or SSD performance?

The Noctua parts are reliable, but they are usually poor value. A Thermalright Peerless Assassin or Phantom Spirit can cool the 7800X3D extremely well for much less money, and its fans can be configured with a quiet custom curve. Arctic and Phanteks also offer excellent case fans at lower prices.
Large dual-tower coolers do not necessarily block the RAM. Many can have the front fan raised slightly, or you can use low-profile memory and check the cooler’s clearance specifications before buying. The NH-U12A is a reasonable compact option if you value guaranteed memory access, but it costs a lot for its performance.
The 7800X3D is more than sufficient for League, Age of Empires II, The Sims, and similar games. Cities: Skylines II can become CPU- and simulation-limited, but the processor is still a strong choice. At 5K2K, the graphics card will usually be the limiting component.
The RX 9070 should handle your lighter games well, but 5120×2160 is more demanding than standard 4K. If the price difference is reasonable, the 9070 XT gives you more headroom and is probably the better long-term choice. Sapphire, PowerColor, and XFX generally have strong AMD card reputations; compare reviews for noise and temperatures rather than assuming any one model is automatically perfect. Coil whine is sample-dependent and cannot be guaranteed away.
A sensible way to rebalance the budget would be to keep the Fractal North if you love the design, replace the expensive cooler and fan bundle with good-value alternatives, and put the savings toward the RX 9070 XT. The case’s stock fans are not necessarily unusable, and you can replace them later if noise is higher than you want.
Use a custom fan curve and make sure the case has a clear front intake and rear exhaust path. An 850 W quality ATX 3.x power supply is ample for either graphics card. Also verify the GPU’s physical length and power-connector position against the case before ordering.
The X870E board is difficult to justify unless you specifically need its integrated 10 GbE, extra connectivity, or its appearance. A cheaper B850 board plus a 10 GbE PCIe adapter can save a substantial amount, although you should check the slot layout. The adapter needs to remain in a slot with adequate clearance beneath the graphics card, and some inexpensive 10 GbE adapters are known to run hot or throttle.
If the Asus board’s looks and built-in networking are important to you, paying extra is understandable. Just make sure the board has the rear I/O and expansion layout you actually need. The 32 GB memory kit is enough for this workload, and a DRAM-equipped SSD may offer steadier sustained transfers and better behavior during heavier multitasking, but it will not improve gaming FPS.
My main concern is avoiding a difficult build or interference with the RAM. Memory availability is poor here, so I would rather not limit myself to unusually short modules. Are there any dual-tower coolers that are known to leave the memory slots accessible?
