Asound a-3905 4 port nic

[brcisna]

Hello All,

Has anyone here any experiences with the Asound a-3905 4 port pci nic card? I am going to use Ebox for the first time and will be needing two wan's and three Lan's,  so i will need a 4 port nic,( along with the onboard nic) or 2 dual port nics, Will the throughput be bottlenecked with the 4 port nic being on one pci bus slot? I m not sure how that all calculates out? I m sure some real nerdy techy person would be able to calculate some figures on this scenario. Not ME!...
BTW: This card uses the generic Realtek 8139 chips.

Thanks
BC
