If your equipment is not up to the higher speed why would you upgrade? QoS is not going to be an issue with older equipment as it will not saturate your connection.

When I upgraded to gigabit my old i3 intell cpu with a gigabit interface could not do full gigabit.. Getting a faster laptop I could. I then found my Tp-Link gigabit switches could not do full gigabit. Definition get a better laptop for 500 Mbit service.
