Help! Struggling with FPS Drops After Upgrading to 5090 and 9800x3d

I've recently upgraded my system to a 5090 GPU and a 9800x3d CPU, having previously used a 3080 and a 5900x. Initially, I noticed good performance in Cyberpunk at 1440p with DLSS set to Quality and Frame Generation x2, but I started experiencing noticeable stutters. After benchmarking with MSI Afterburner, I discovered some concerning 1% and 0.1% low FPS numbers. I expected a significant performance boost with the new CPU upgrade, but the improvement was minimal, around 5-10 FPS. I've done extensive research and made many adjustments, yet I'm still experiencing deep FPS drops in games like Street Fighter 6, which used to run smoothly on my old setup. Here's a rundown of my current specs: - GPU: 5090 FE - CPU: 9800x3d - RAM: 32GB DDR5 6000 MHz - Storage: 2 TB NVME WD PCIe 4.0 - Motherboard: GIGABYTE B850 AORUS Elite WIFI7 - PSU: NZXT C1200 Gold ATX 3.1 - Monitor: 1440 360Hz OLED Despite trying a fresh Windows 11 install, adjusting BIOS settings, and various driver updates, my gaming experience is hindered by these persistent FPS drops. Any advice or insights would be wonderfully appreciated!
