Depends on what you are going to use your Linux box for, home box it's
not that critical. On a large scale environment that network card
would be more interesting since it can scale I/O interrupts in a way
that require less work for the CPU in high traffic environments
compared to a conventional network card etc. It is indeed a huge
difference between desktop and server hardware as you will also notice
on the price tag.. ;)
