I am currently debating upgrading my router from a Asus n66u dark night to a Asus rt-ax88u. In the event I do I need to upgrade my wireless card on one of my PC's and am hoping moving my server to wireless. I have been looking for pcie wireless cards and the two I've been look at are Asus PCE-AX58BT/ 2x2 Or Asus PCE-AC88/CA 4x4. I am curious on which card would be the better to choose for both reception and transfer speeds. Thanks for any info anyone can provide.
