My rationale is to avoid consumer grade products, rather leverage the work of engineers that qualify equipment for data centers, i.e. the data center market is driving the vendor.   I find the INTC server class NICs to be the best for this so far.

I figured as much, and might take it into account that you’re steering me towards those NICs. I’m pretty sure the I350T2V2 would work well, so I started another build with it, despite the price:

My latest thought is, if I get a good dual port NIC and go at least a bit higher-end with the CPU, I shouldn't need a second device, and time synchronization won’t be an issue, so it could save some effort. I’ll try a few more options, sleep on it and thanks everyone for the help!
