My PC I just built, a Ryzen 5950x with an X570S chipset, has the least PCIe slots I've ever had on a PC. (3) Plus... if you use the second slot, it cuts your graphics card down to x8 PCIe lanes, so no way !!! And if you use the third slot, it disables one of the on board NVME drive slots. This I had no choice. So, in the end I had room for the graphics card and a single 10 gigabit ethernet adapter.
