I don't think so - would need to see the block diagram for the mobo, I just dont think the chips on these cheaper 10GbE Nics are as good as the Intel or Mellanox alternatives.
The 10GbE NICs I tested were all on a PCIE slot directly connected to the CPU - and I've just corrected my post, its not ASMedia who are producing the chips on the NICs its Aquantia
Gotcha.
Intel NIC's are hands down the best I've used. The only problem is usually price.
