I bought a custom-built gaming PC about a month ago with a Ryzen 7 9850X3D, RTX 5080, and 32 GB of RAM. This is my first gaming PC, so I'm still learning the basics. The system feels much slower than I expected: games have low FPS, and switching between browser tabs can feel sluggish. I've checked Task Manager and the listed hardware appears to match what I bought. The monitor is connected to the graphics card, Windows was freshly installed by the seller, and NVIDIA drivers were installed. What should I check or change to make sure the PC is running at its best?

“Slow” can mean several different things, so it would help to record your FPS, monitor resolution and refresh rate, game settings, temperatures, and CPU/GPU usage while gaming. Without that information, it’s difficult to identify the cause. A powerful PC should not generally feel slow, but the problem could be settings, drivers, thermals, storage, or something else.
Since the PC was bought used, verify the actual parts with tools such as Task Manager, GPU-Z, or CPU-Z rather than relying only on the seller’s description. Check that the RAM is running in dual-channel mode with its advertised memory profile enabled, and make sure games are installed on a healthy SSD with plenty of free space. Posting the exact game, FPS, resolution, refresh rate, temperatures, and usage percentages would make troubleshooting much easier.
Check the monitor’s refresh rate in Windows display settings. Setting the correct resolution does not automatically set the monitor to its highest refresh rate, and being stuck at 60 Hz can make games and desktop movement feel noticeably less smooth. Also make sure the monitor cable is plugged into the RTX 5080 rather than the motherboard.
The cable is connected to the graphics card, and I checked the monitor settings. I may still have expected more than the system can deliver, though.
Install the latest chipset drivers for the motherboard and the current NVIDIA graphics driver, then check Device Manager for warning symbols. Confirm that the graphics card is installed in the motherboard’s main full-length PCIe slot and that its power cables are fully seated. You can also watch temperatures and clock speeds while gaming to see whether the CPU or GPU is overheating and reducing performance.
The parts appear correctly in Task Manager, and Windows was freshly installed before I bought it. I’m still new to PCs, so I may need help interpreting the other information.
