Heh... gotta laugh at HateFury for advising and getting +rep in this thread considering his big rant on Gigabit per his sig. (and yes.. we realize you gave the advice here because the user ASKED for faster transfers and didn't just assume he just wanted a "generic flavored" network based on cheapest cost alone.
This thread seems "tailor made" considering that previous discussion.
And yes, I would've recommended the same thing... get a Gigabit switch (cheaper than the Gig router plus you don't need the extra speed for your internet connection), make sure your NICs are "gigabit capable" (or if not, upgrade to Gigabit NICs in your networked PCs) and rock and roll with a faster network connection between computers.
Either way bruestle2 got some sound advice in this thread.
Good luck with your network
