Don't forget that you need cables that are rated that speed also.
What is it Cat 6 for Gb, or Cat 7?
I know the high performance Cat 5 I run is ony rated up to 350Mb.
10% of a Gbit connection is called Fast Ethernet, Gbit goes between 20-40MB/s usually. Cat5 are rated for Gbit, though never designed to do such speed, Cat5e or even cat6 are your safest bets.
