The MSI Gaming MX 5600 XT says on the box that it is PCIe 4.0. Does this mean I need a motherboard with a PCIe Gen 4 slot? If so, what motherboard do you recommend, please?
The slot is backwards compatible so it can drop into a PCIe 3.0 x16 slot. Any B550 chipset motherboard will do if you want to jump into PCIe 4.0 connectivity.
