Only in WAN such as online games and file downloading but in LAN the gig switch will do good.
Routers are hard to buy nowadays. I have a bunch at home but they did not meet my needs and money was wasted. They work fine for the average network but do not play well with heavy usage.
You could either buy a higher end one such as AMPed wireless or use an old machine to build one.
