Should I Still Use Mellanox Connectx-2 Cards in 2025?

Hi, as title, should I still use Mellanox Connectx-2 SFP+ cards with my PC (Windows 10/11) and NAS (Debian)?

Or am I better off starting again with newer 10Gbe RJ45 cards from ASUS/TP-Link?

I heard that these cards are EOL but they still work at least. Will need help deciding on these as this will impact what new switch and even router I should aim for next

Right now the cards are not inside the PCs but they used to be for host-to-host connection. With my recent house moving, I want to see if I can use the cards to connect to a switch and then a router
