I'm struggling to find a reason to move to 2.5gbe, let alone 10gbe... and my latest system build at least has 2.5gbe on the motherboard. My problem is everything else... NAS boxes, security cameras, other PCs... all 1gbe, so what is my urgent need to upgrade? I have to Linux PC Servers that... maybe... I could upgrade to 2.5gbe, but the motherboards are pretty ancient.
