A few years ago, I built my PC and it has generally run smoothly without any significant performance issues. Here's my current setup: Gigabyte Z690 DDR4 motherboard, Intel i5 12600K CPU, 32GB of DDR4 RAM running at 3600 MT/s, and a GeForce RTX 3080 GPU. Recently, I replaced my local disk with a larger NVME SSD, and since that swap, I'm experiencing a drastic drop in performance that I can't pinpoint. I ran a Passmark performance test, and my system scored 2389.4, placing it in the 23rd percentile, which seems quite low. What can I do to figure out what's causing this decline in performance?

Have you checked if your Windows install is bogged down by background apps? Also, if you still have any old SATA SSDs connected, they could be affecting overall performance too. Make sure your thermal management is good! Your 3DMark score isn’t bad, but systems like yours usually perform even better. Keep investigating, possibly it might be an issue with Windows.
One simple test you could do is swap out the new SSD for your old one. If that resolves the performance issues, then it’s likely the new SSD that’s causing the problems.
That’s strange! A simple SSD change shouldn’t cause such a drop. You might want to check if the NVME is faulty or if your Windows installation is messed up. I'm considering doing a clean install of Windows myself after years of upgrades since Windows 7. If you go this route, updating your motherboard firmware before reinstalling Windows could also help. Good luck!
