I'm putting together a PC in Switzerland with a budget of roughly 2,000–2,500 CHF. It will mainly be used for Microsoft Office and LaTeX work, with occasional gaming such as League of Legends, Age of Empires II: Definitive Edition, Cities: Skylines, and The Sims. Gaming will be done on my existing LG 40WP95C-W, a 39.7-inch 5120×2160 monitor running at 72 Hz.
The proposed build uses a Ryzen 7 7800X3D, 240 mm Corsair AIO, Asus ProArt X870E-Creator motherboard, 32 GB DDR5-6000 CL38 memory, a 2 TB PCIe 4.0 NVMe SSD, Radeon RX 9070 XT, Fractal North case, 750 W Seasonic power supply, and several Corsair fans. The prices shown in the parts list are from another market and do not represent Swiss pricing or availability.
I'm considering the Asus board mainly for its appearance and dual 10 GbE connectivity. The Gigabyte B850 AI TOP also has two 10 GbE ports and costs about the same locally. Is there any meaningful reason to choose one over the other besides features, connectivity, and aesthetics?
The RX 9070 XT is only about 50 USD more than an RTX 5070 here. Is the Radeon the better choice for these games and this high-resolution monitor, or does the RTX 5070 offer important advantages outside CUDA, ray tracing, or specific software support?
I could wait a week or two for a matching Fractal AIO and fans, but the Corsair parts are available immediately. Is there any practical reason to wait, or is the difference mainly visual? I'd also appreciate suggestions for improving the build, keeping in mind that Swiss prices and availability are very different from typical online part lists.

The motherboard, cooler, and case fans do not need to be from the same brand. Mixing Corsair and Fractal parts will not hurt performance; the main considerations are fan control, ARGB headers, radiator fit, noise, and whether you want to manage multiple lighting ecosystems. Check the radiator thickness and top clearance in the Fractal North, then choose the immediately available parts if the design is acceptable to you.
Also check the total price of the SSD and motherboard locally. For office work and the games listed, a less expensive X870 or B850 board and a similarly good 2 TB NVMe drive would feel the same in everyday use unless the additional 10 GbE and creator-oriented I/O are genuinely useful.
The memory specification is not ideal on paper: DDR5-6000 CL30 is usually the sweet spot for Ryzen 7000, while CL38 is slower. However, if CL30 kits cost dramatically more in Switzerland, the real-world difference is small and buying the affordable kit is perfectly reasonable. Make sure the kit is an EXPO model and enable EXPO in the BIOS.
The 9800X3D would be faster in CPU-limited games, but with a 5K2K monitor and an RX 9070 XT, you will often be GPU-limited. For short sessions of the games listed, the 7800X3D should already be excellent, so the upgrade may not be noticeable enough to justify a large price increase.
For premium AM5 motherboards, the practical differences are mostly connectivity, expansion options, BIOS features, and appearance. The VRMs on both boards are more than sufficient, so there is unlikely to be a noticeable performance difference. If you genuinely need two 10 GbE ports, compare the exact rear I/O and PCIe/M.2 lane layout; otherwise, a cheaper board could do the same job and the savings might be better spent elsewhere.
The RX 9070 XT is generally the stronger gaming card at this price, especially at 5120×2160, unless you specifically need CUDA, Nvidia-only software features, stronger ray-tracing performance, or particular upscaling/encoding features. For the listed games, those Nvidia advantages are unlikely to matter much.
Matching the AIO and fans is primarily an aesthetic decision. A 240 mm cooler is already plenty for a 7800X3D, and a good dual-tower air cooler would also be sufficient. Arctic Liquid Freezer models are worth considering if they are available at a good Swiss price.
A 72 Hz monitor is not automatically a bad gaming display. For casual gaming at around 30 minutes per day, it is a reasonable compromise, especially if the monitor is much better suited to your office and productivity work. The bigger challenge is driving 5120×2160 at high settings, so use sensible settings or upscaling where needed rather than expecting maximum frame rates in every game.
The 750 W supply is probably adequate for this system if it is a good-quality unit, but I would prefer a current ATX 3.0 or ATX 3.1 model with a native 12V-2x6 connector where possible. That is mainly about modern cabling and future compatibility, not because this particular build necessarily needs more wattage. Keep the existing Seasonic option if it is substantially cheaper and has the appropriate connectors, but don’t pay an unusually high premium just for the brand.
The two 10 GbE boards are almost identical in price here, and the Asus wins for me visually. The selected RAM, PSU, and graphics card are also the cheapest suitable options currently available in Switzerland, so US pricing doesn’t really reflect the actual choices I have.
