I recently assembled a new PC and thought the components were solid. Now I’m concerned the performance might be lower than expected, especially with the number of PCIe lanes you have. Your setup includes: 6950XT ASROCK OC GPU, AMD 7 7700X CPU, MSI B650 motherboard, Wi-Fi, and a 1TB Kingston SKC3000S storage with two 2TB Samsung 980 PRO drives over PCIe 4.0.

No need to worry about lane count—PCI-e is the standard here. Can you share your CPU temps and cooling setup? Also, what’s the case design like? Are your fans properly installed?

I mean a lack of effectiveness or quality in delivering results.

Have you started with a brand new Windows setup or are you continuing from an existing version?

Websites loading slower than my older system, but depending on different game benchmarks compared to others with similar configurations. I’m still getting comfortable with the technical side of PCs, so please forgive any confusion! Just starting with a fresh Windows 11 installation.

This happens because too many M.2 NVMe drives can overload the system. As a result, SATA or PCI slots are turned off to prevent issues.

You can utilize enough lanes to turn off specific ports on the motherboard, though this won’t impact performance—it would simply completely block a connection. What I was trying to say is that there’s no way to overload the system with too many lanes. The only real issue could be that certain slots might split or become disconnected, but this wouldn’t affect the GPU in the top slot or the CPU at all.

A new update for w11/nvidia drivers caused hardware acceleration to fail on the desktop. Check the settings and turn off hardware acceleration.

You can also remove the main GPU slot from x16 to x8 when there are too many lanes. On many GPUs this doesn't impact performance, though it does more significantly on high-end models.

Yes, it won’t noticeably slow things down. Usually you’d lower performance to around x8/x8, which is needed in BIOS and works best with dual high-end cards. Instead of putting all the CPU power into one slot, it splits the first slot and provides lanes for both GPUs, reducing latency. On the Z790 chipset, you can move the 5.0 slot to 8x 5.0 and free up space for an M.2 drive, letting you pair it with a 5.0 SSD.
