    It was never just for graphics cards. It's a replacement for the PCI bus. It just happened to also replace AGP, which was a dedicated graphics port.
    It's commonly used for network cards, audio cards, storage (NVMe is PCIe), etc.
    Thunderbolt is PCIe + DisplayPort

    Don't worry, Microsoft will make sure new AMD CPU's aren't compatible with Windows 7, just like Intel CPU's
    AMD officially don't support Windows 7 for Ryzen or Threadripper CPU's.

    It's going to get harder and harder to get drivers for Windows 7 for either platform.
