Chances are your computer already has gigabit ethernet... if you start 
to see problems then add a gigabit switch and you should be good.

The HDHomeRun has hardware PID filtering and most HDTV streams are a 
little under 10Mbps per channel so your typical throughput for two 
tuners would be around 20Mbps.

Regardless of the interface (PCI, USB, Firewire, Ethernet) you have the 
same bandwidth requirement. Ethernet as a protocol is very low overhead 
and the linux drivers are usually very good. USB in particular is bad 
for overhead. PCI cards usually don't do PID filtering so your computer 
has to process the full stream bandwidth even though it is going to 
throw the other sub channels out.
