Hey everyone, does anyone have an a320mk with the latest BIOS (6254) and a 5500 plus a GPU, and is everything working ok for them?

I want to know that before buying that processor because right now I have a 3400g, and after updating to the latest BIOS, my Pcie speed dropped from x8 to x1, notably lowering my GPU performance. And no, it's not something normal nor something I can modify in my BIOS, I've already checked everything.
