In short: No.

The longer version is: Depends.

Remember that if you have, say, 2Mbit ADSL, the actual data throughput
is likely to be significiantly lower than that. While the line speed
itself is actually faster than 2Mbit (to take account of the ATM
encapsulation overhead), there is still a PPP and IP overhead to account
for).

The network link between your PC and the router is not going to run at
1000Mbit, unless both ends are capable of doing so. This is unlikely
with ADSL routers. A number of single port ADSL routers have only a
10Mbit interface. At dsl line speeds of 2Mbit, this is unlikely to be a
bottleneck. Even my MicroVAX, with it's 10Mbit AUI port and external
UTP tranceiver, can keep up with that.

What is far more likely to slow down your connection is packet
inspection by firewalls. If you are behind a NAT router, do you really
need inbound packet inspection? If you use a non-swiss-cheese-edition
browser/mailer, keep up to date with security updates, and do not run
arbitary software on your machine, do you need a firewall on the machine
at all? Obviously, if you are running software you do not trust, or you
expose any part of your system to unsolicited connections from outside
your network, you do.

Finally, it is unreasonable to expect more than about 58k/sec download
for an optimised connection on 500k DSL. And that is for a single large
file, via FTP, with nothing else going on. Any conversation that
involves lots of HTTP GET requests, cookies going back and forth, etc,
will provide far less than that, even on a good day.
