Hello, I checked if the Ryzen 5 5600G can work with a PCIe Gen4 GPU. Your motherboard is an ASUS ROG B450 Gaming II with PCIe Gen3 support, and you have an AMD R9 270X XFX PCIe 3.0 slot. You're planning to switch to an MSI RTX 3060 Gaming X Trio, which uses a Gen4 interface.

It should function properly, though performance will be capped at 3.0 speeds. The variation is small enough you probably won’t detect it. No extra changes, just a few games take advantage of it without much impact.

PCIe supports both backward and forward compatibility. A device from one generation can fit in a slot from another generation, and vice versa. You can install a Gen 1 unit in a Gen 4 port and it will function. Similarly, a Gen 4 device works in a Gen 1 slot. The only limitation is using a longer slot length in a shorter slot on the motherboard (such as placing a GPU in an x1 slot), though some boards have open-ended slots where extra length can hang freely without needing a connection.

Searching online suggests most 1.0 motherboards likely won’t support newer components, but this seems less relevant since such hardware is rarely used anymore. I’m mainly familiar with systems from around 1.1, so I don’t have firsthand experience.

Actually, it hasn't completely disappeared, though very rarely today. Boards continue to receive BIOS updates that handle PCI-E compatibility challenges. Back in the 2005-2008 period, new GPUs often failed to work with many chipsets. Still, you might occasionally find BIOS updates mentioning (PCI-E device compatibility/stability) for current boards, but the issue is much less frequent now since AGP is no longer being phased out.

I’m really comfortable with that typing style, so I’ll just close this thread. It looks like things are heading pretty far into a debate about pride versus actual computer knowledge.
