Should I move to AM4, AM5, or stay with DDR4 for my RX 6800 XT?

I recently bought an RX 6800 XT, but my current i5-10400F seems to bottleneck it in games such as Cyberpunk 2077. I'm playing at 1080p, and GPU usage can drop as low as 17% in areas with lots of NPCs. My current memory is 32GB of single-stick DDR4-3200 CL22. AM5 systems are expensive where I live, and selling my current memory might only let me afford 16GB of DDR5-5600 CL46 in a single stick. Would it make more sense to move to AM4, switch to AM5 with that memory, keep my DDR4 and upgrade the CPU and motherboard, or simply wait? I also plan to replace my hard drive with an SSD later.

I wouldn’t move from your current platform to AM4. It would be an older dead-end platform, so the upgrade would give you limited future options. If AM5 is too expensive, keeping DDR4 and moving to a stronger CPU and compatible motherboard is probably the better value. A Core i5-13600KF or 14600KF with a DDR4 B760 board could provide a large improvement without forcing you to buy DDR5 immediately.

Before spending money, check whether the CPU is actually limiting you in the games you play. At 1080p, Cyberpunk can be CPU-limited in busy areas, especially with an RX 6800 XT, but at higher resolutions and settings the GPU becomes more important. An i5-11600K could be a relatively inexpensive drop-in upgrade if your motherboard supports it, though the performance increase would be fairly modest.

If you choose AM5, avoid building around 16GB of single-channel DDR5. One stick reduces memory bandwidth and can hurt minimum frame rates. A 32GB dual-channel kit, typically two 16GB modules, is a much better target. AM5 offers the best upgrade path, but it may not be worth stretching your budget right now just to end up with slow, single-stick memory.

The sensible budget choice is probably to keep your DDR4 and upgrade the CPU and motherboard, or wait until you can afford a proper AM5 setup. An AM4 build only makes sense if you find a very cheap used bundle; buying an expensive high-end AM4 processor such as a 5800X3D would not be good value in this situation. An SSD should also noticeably improve loading and streaming compared with the hard drive, although it won’t fix a CPU bottleneck.
