2.5Gbs standard is designed to tolerate the interference on Cat5e. So Cat5e is not quite dead and berried yet. Yes a link that fails 1000Gbe on Cat5E can magically work perfectly at full speed when you use the new 2.5Gbs cards. So 2.5Gbs instead of the 1000Gbe.
Tolerance of adaptors/switches to interference is a big factor how fast you can go over Cat5e.
Yes the new 2.5Gbs stuff is a nice curve ball to make this even more confusing if you should spend money on Cat6A or better.
