My i5-13600K system has become unreliable. Discord, Voicemod, and other applications sometimes freeze or become sluggish, and I occasionally get complete crashes with a black screen that require a restart or even unplugging the PC for a while. I have already updated the BIOS, reseated the RAM, disabled XMP, changed some BIOS settings, and checked for malware, but the instability continues. I'm wondering whether the CPU may have been affected by the known 13th-generation Intel issues. I already have 32GB of DDR5, so switching platforms would require a new motherboard and CPU. The current prices I'm seeing are about $320 for a 7800X3D and $430 for a 9800X3D. Is the 9800X3D worth the extra money, especially for gaming with a 9070 XT, or should I choose the cheaper 7800X3D?

A 13600K should still be plenty for gaming and shouldn’t create a major bottleneck, even with a high-end graphics card at 1440p. If you replace it anyway, the 7800X3D is usually the better value at $320. The 9800X3D is roughly a modest step faster rather than a night-and-day upgrade, so the extra $110 is mainly worthwhile if you want the fastest option and plan to keep it for several years.
Those symptoms aren’t automatically proof that the CPU is bad. A failing NVMe drive can cause applications to freeze, crashes, and even system-wide hangs, so check the health of your storage and try running from a known-good drive if possible. A clean Windows installation is also worth considering before replacing hardware, even though it is inconvenient.
Before buying a new platform, contact Intel about an RMA. The 13600K is covered by an extended warranty, and a replacement may solve the problem without the cost of a motherboard and CPU upgrade. Make sure the motherboard is running the latest official BIOS as well, although a BIOS update may not repair a chip that has already degraded.
The newer microcode helps prevent or slow damage, but it is not necessarily a permanent fix for a CPU that was already affected. A replacement is the safer route if the processor is unstable.
Some people who moved from 13th-generation Intel to AM5 preferred the 7800X3D because it offers excellent gaming performance and costs less. The 9800X3D is faster, but the difference is often smaller at higher resolutions where the GPU is doing most of the work. Since your issue is system stability rather than performance, I’d diagnose or warranty-replace the 13600K first instead of assuming a new CPU will fix everything.
I’ve mostly focused on the BIOS and RAM so far, but checking the SSD and trying a clean install makes sense before spending money on a new platform.
