I stopped using PCI / PCIe cards for network a while ago in favor of USB network cards. Easier to use a short USB extension cord to put the USB adapters in a spot for good reception then to buy reverse-SMA antennas for the PCI cards, and the install is much easier.
Make sure and then double check again that the card you buy works well with windows 10. Many win7 cards have problems with win10. (note, some of the usb sticks I stopped using e.g. netgear wnda3100 and linksys wusb6300 that did not work at first now work acceptably on both 2.4 and 5ghz bands, so people are moving forward with drivers for older network gear, just slowly.)
for pcie card you wanted, here's one...
