I would say yes.  In an ideal environment, you should not have any errors.  
Also, you should not have any collisions if you are running at full duplex.

What is brand/model of NIC in your box?  I had problems with my Linksys 
LNE100TX NICs lately.  I had a newer version (5.1?) of the LNE100TX in my 
server and it would drop off the network completely, which required a soft 
reboot.  I swapped the newer version of the card with an older version and 
the server has not dropped of the network once.  I currently have an uptime 
of 27 days, 43 min; which is better than before.  My server used to drop 
off the network once a day.
