That link has a lot of bogus information. "Unless every single component in the network is gigabit rated, then you will never have a gigabit network, because your network will always run at the speed of your slowest device." - That simply is not true.

Cat5E cable is cheaper than Cat 6. If you had a contract for cat6 and particularly if you got charged for cat6, then you are getting ripped off. As far as actual internet throughput, you will not see any difference whatsoever unless you have a very long cable run.
