I'm comparing two Micro Center bundles. The first includes a Ryzen 7 7800X3D, 32GB of DDR5-6000, and a Gigabyte X870 Gaming motherboard for $769.99. The second has a Ryzen 7 9800X3D, 32GB of DDR5-6000, and an MSI X870E-P Pro for $949.99.
I'll be using the system with an EVGA RTX 3080 FTW Ultra, mostly at 1440p on a 144Hz monitor. I play a lot of Rust, which can be demanding and seems to benefit from the extra cache on X3D processors. I also need a new case, CPU cooler, and power supply. Would a quality 750W PSU be enough, or should I buy 850W or 1000W?
Is the 9800X3D actually worth the roughly $180–$200 premium for this setup? Is the MSI X870E motherboard meaningfully better than the board in the 7800X3D bundle, or would I be better off saving the money for a future GPU upgrade?

With an RTX 3080 at 1440p, the GPU will usually be the limiting component, so the 9800X3D probably won’t deliver a noticeable average-FPS improvement over the 7800X3D. The difference is more visible at 1080p with a very high-end graphics card, or in CPU-heavy esports games. Rust can be CPU-intensive, but your actual results will depend heavily on the server, settings, and how much the GPU is being used. I’d take the cheaper bundle and put the remaining money toward storage, cooling, or a future graphics card.
The 9800X3D is the faster and newer chip, but it isn’t roughly 20% faster in this situation. At 1440p with a 3080, the practical difference will often be small. The X870E board does offer a higher-end chipset and may provide more connectivity, such as additional or faster NVMe support, but it won’t make the CPU perform significantly faster. Check the exact slot layout and USB features to see whether you need them. For power, a good-quality 750W unit is generally sufficient for a stock RTX 3080 and either CPU; 850W is a comfortable upgrade, while 1000W is unnecessary unless you plan on moving to a much more power-hungry future GPU.
The second bundle could still be worthwhile if I specifically want the extra NVMe slots and newer platform features, but I shouldn’t expect the motherboard itself to add gaming performance.
I’m specifically playing Rust at 1440p, so I was wondering whether its CPU-heavy performance changes the recommendation. I’m also worried I’ll regret not buying the newer processor.
