I'm planning a modest upgrade to my PC, which has been mostly unchanged since 2018–2019. It currently uses a B450 Aorus Elite motherboard, Ryzen 7 2700, GeForce GTX 1080 Ti, and 32GB of DDR4-3000 memory. I'd prefer to stay on AM4 for now because current RAM prices make a newer platform less appealing, and I'm mainly interested in the best price-to-performance ratio rather than wasting money on unnecessary upgrades.
For the CPU, I'm considering the Ryzen 7 5700X, 5700X3D, 5800X, or 5800X3D. I use Lightroom and Photoshop, but I also play a variety of games and would like the system to handle GTA VI if it eventually releases on PC. Is the extra cost of an X3D processor worthwhile for this mixed workload, or would a standard Ryzen 7—or even a Ryzen 9—make more sense?
For the GPU, I've been looking at a used RX 6800 XT. I also considered the RX 7800 XT, but the performance difference seems fairly small, and I'm not especially interested in upscaling features. Is a used 6800 XT still a good choice in 2026, or would another AM4-compatible upgrade offer better long-term value? The system is connected to a 34-inch ultrawide 1440p monitor.

Before buying, check whether your B450 board has a BIOS version that supports the Ryzen 5000 chip you choose. You may also need to update the BIOS before removing the Ryzen 7 2700. Enable XMP or DOCP for the memory, and make sure the used graphics card has good temperatures and no obvious signs of mining abuse. At an ultrawide 1440p resolution, the GPU will usually matter more than the difference between two high-end AM4 processors.
I’d compare the entire used-market setup rather than locking into one part. A 5600X3D or 5700X3D paired with the best GPU you can afford may outperform a 5800X3D paired with an older or much weaker card at 1440p. Depending on local pricing, newer options such as an RX 9060 XT, RX 9070, or a used RTX 4070 could provide a better balance than spending everything on the CPU.
For gaming, a Ryzen 7 5700X3D or 5800X3D would be the strongest AM4 upgrade. The extra cache can make a noticeable difference in CPU-heavy games and should help keep frame rates smoother at 1440p. Your 1080 Ti is still usable, so you could upgrade the CPU first and save for a stronger graphics card later instead of buying a cheaper GPU immediately.
Your workload matters here. Lightroom and Photoshop generally benefit more from extra cores and strong general-purpose performance than from 3D V-Cache, so a Ryzen 9 5900X or 5950X can be a better productivity choice if you find one at a reasonable price. For a mixed gaming and editing system, the 5700X3D is a good compromise, while the 5800X3D only makes sense if its price is close enough.
A used RX 6800 XT can still be excellent for standard 1440p gaming if the price is low enough. It has plenty of rasterization performance and 16GB of VRAM, but ray tracing performance and future driver support are weaker than on newer cards. If the 7800 XT is only around $100 more, I’d choose it for the newer architecture, longer support outlook, and better feature set. Otherwise, the 6800 XT is the better bargain.
That was my concern too. Since the CPU upgrade is relatively affordable, I may keep the 1080 Ti for a while and put the remaining budget toward a newer GPU later.
