Will a PCIe 3.0 x1 slot bottleneck a Dual Port Gigabit PCIe card?

[Ja55ie]

Hi, I have a motherboard with an extra PCIe 3.0 x1 slot. I wanted to put a NIC like this Dual Port Gigabit PCI Express Server Network Adapter Card and was wondering if the PCIe 3.0 x1 will bottleneck a 2-port gigabit card that's using full bandwidth. Let's say I configure it to Link Aggregation/LACP and make it effectively 2gbps. Will the PCIe 3.0 x1 slot bottleneck this card? 

If so, how much of a hit would it take?

 

Thanks,

Probably be fine. PCIe 3.0 1x should be capable of at least 750MB/s in each direction with overhead and everything accounted for. Dual gigabit would peak at 250MB/s

Thank you! So theoretically, I would be able to use a 3-port NIC and *hopefully* not experience any bottleneck.

No worries!
