My Ryzen 5 5600X has failed, so I'm considering moving from AM4 to AM5. The system is mainly for 1440p gaming on an Alienware AW3426DW, including Battlefield 6, Forza, Total War, GTA V, and Red Dead Redemption 2, but I also want to explore AI tools, agent workflows, office work, and multimedia tasks. I'm flexible on framerate and have around $1,750 AUD to spend in Australia.
The parts I'm considering are a Ryzen 7 9700X or 9800X3D, an X870 Eagle WiFi or Gaming X motherboard, a Thermalright Peerless Assassin 120 SE, and 32GB of DDR5 RAM. I already have a Fractal North XL case, an MSI RTX 3080 10GB, a 750W Gold Cooler Master PSU, two M.2 drives, and two SATA SSDs. I may upgrade to an RTX 5070 Ti or RTX 5080 later.
I'm interested in a motherboard with good long-term connectivity, including multiple USB-C ports, USB4 support, WiFi 7, and enough storage expansion for an external SanDisk Professional drive. I'm not planning to do much overclocking. Is the 9800X3D worthwhile for this mix of gaming and productivity, or would the 9700X—or even staying on AM4 with a 5700X3D—be the better-value choice? Also, would a higher-end B850 board make more sense than a lower-cost X870 model?

Before replacing the whole platform, consider a Ryzen 7 5700X3D if your existing AM4 motherboard supports it. It would be a relatively inexpensive gaming upgrade and could let you put more of the budget toward a future GPU. Moving to AM5 gives you newer connectivity, DDR5, and a longer upgrade path, though, so AM5 is reasonable if USB4, WiFi 7, and future expansion are important to you.
At 1440p, a 9800X3D is likely poor value with an RTX 3080 because the GPU will usually be the bottleneck. Even a 9600X or 9700X should be plenty for current gaming, while the 9700X gives you a better all-round balance for productivity and AI experimentation. If AI workloads become a major focus, check the software requirements carefully—GPU compatibility and VRAM may matter more than choosing between these CPUs. A future GPU upgrade may provide a more noticeable gaming improvement.
A good B850 motherboard is probably a better buy than a budget X870. In practical use, most people will not benefit from the extra chipset features, especially if they are not overclocking. Focus on the exact board’s rear USB layout, USB4 support, WiFi version, M.2 slots, networking, and power delivery rather than the X870 label. You generally do not need to spend much more than about $200 AUD on the motherboard unless a specific connectivity feature justifies it.
The 9800X3D is the fastest gaming option, but your RTX 3080 will limit the difference at 1440p in many games. It becomes more worthwhile if you later move to a high-end GPU such as an RTX 5080. For a mix of gaming, AI work, office tasks, and multimedia, the 9700X is a more balanced choice. A 7800X3D would also make sense if gaming were the main priority, but it is less attractive for broader productivity work.
That makes sense. I’ll compare the individual USB4, USB-C, WiFi 7, and storage specifications instead of assuming X870 automatically means better. I’m not planning serious overclocking, so the board’s connectivity is more important than enthusiast features.
