I bought my antennas on Amazon and they work great.

My board (Which is a little old now) has an Intel AC7260 card and I have no problems getting a strong 5 GHz AC signal from my router on the opposite side of my house.
The same antenna that goes on the router is what the wireless adapter uses.
What you want are called RP SMA connectors. Higher gain means increased horizontal range, at the cost of vertical. Think of it like a donut, and the more gain you have, the more you squish it down.
The antenna you linked is likely the same or even slightly lower gain than stock. You will want something at least 7-9 dBi, and because your wireless adapter has two, you will need two.

There are more expensive directional options, which provide a larger gain increase, but only in the direction they are pointed.

Positioning can also be an issue, grab some RP SMA cables if needed to move the antennas around. They do reduce the gain by a tiny amount, I don't recommend longer than 2m.
Although better antennas can help, if your wireless access point isn't good then your money is better spent improving that.
These would do nicely

What's your main motivation by trying to replace the WiFi card? If it's range, another option is to just replace the antennas. They're usually just screw-ins, although you have to check if the screws are spaced apart enough for the antennas to fit. Ex: https://www.amazon.com/dp/B00O0O0E8U/
I wouldn't worry much about obsolescence. You're more likely to need a new motherboard than WiFi card by the time the stock WiFi card becomes outdated enough that your speeds are affected.
