I built a new PC a few months ago for streaming, but I've had persistent internet problems that appear to be related to the motherboard's onboard Intel Ethernet controller. I'm considering replacing the board because I don't want to keep troubleshooting unreliable hardware, but I also can't easily afford to return another motherboard if it turns out to be incompatible.
My current system uses a PCIe riser for the graphics card and a capture card. I'm looking at the Gigabyte B650 AORUS Elite AX ICE as a replacement and would like to keep the white theme if possible. My main concern is that the case documentation recommends a PCIe 5.0 riser, while this motherboard may not provide a PCIe 5.0 slot in the configuration I need. Will the board work properly with my existing build and riser, or should I choose a different motherboard? I'm also open to a black or silver board if there isn't a suitable white option.

Before replacing the whole motherboard, consider a PCIe Ethernet adapter or even a USB Ethernet adapter. That could solve the connection problem without discarding an otherwise powerful board. It’s worth confirming that the onboard network controller is actually the cause first, though.
PCIe 5.0 slots use the same physical connector as older PCIe generations, and PCIe is backward compatible. A PCIe 5.0 riser can generally operate with a PCIe 4.0 or older slot, although the connection will run at the lower generation’s speed. You may need to manually set the slot to Gen 4 or Gen 3 in the firmware if the system is unstable.
The riser requirement may depend more on the case and the graphics-card layout than on the motherboard itself. Check which slot the riser connects to and whether the board supports the required lane configuration. Also, compare manufacturers’ warranty and replacement policies before buying, since customer service can matter just as much as the board’s color or specifications.
