No such thing as already set up, dude :) There are high end routers that are marketed towards gaming, I use a 4 year old Netgear WNDR 3700, cost me £100. If I had to buy a new router it would be a netgear nighthawk (yes there are several). I am not recommending that you buy a new router (unless your current one has sparks coming out of it and is held together with duct tape) Probably your current router will be fine and has many features available to you, but it still requires the advanced features to be set up for your particular priority and devices
