mac pro 2013 wireless card upgrade

That model Mac Pro 2013 appears to have three antennas. That means its top speed when close to the Router could be about 540 M bits/sec. Does your Router (and your network neighborhood) support 80 MHz channels? That has the potential to increase top speed to about 1200 M Bits/sec.

If you current results are no where near those numbers, switching to 802.11ax will likely NOT provide a remarkable improvement.

under IDEAL conditions close to your Router, 802.11x with a 40 MHz channel can provide up to about 270 per antenna, or 810 Total, and 80 MHz channel, up to about 575 per antenna, or 1725 per total.

Consider moving your Router closer and connecting via Ethernet. That late 2103 Mac Pro has TWO Gigabit Ethernet ports and they can be used together if you have equipment that supports using both at once.
