Lately, I've seen several X550-T1 network cards on Amazon from multiple Asian sellers listed for around $60. I've also seen on eBay what looks like Intel OEM cards (also from Asia) that include Intel-labeled driver cds for around $150, but if the $60 would work OK, it seems a no-brainer to buy them. Anyone here ever try these $60 X550 NICS? Failing that, where can one find used Intel X550 OEM cards?
