I'm considering upgrading my current DD-WRT micro equipped router to something more powerful. I am interested in a router than handle atleast double the amount of connections my router can currently (4096) to better handle BitTorrent traffic when it's maxing out my connection bandwidth (16mbps/2mbps). On top of that I would want to create a gigabit lan for streaming 1080P video throughout my home.
For this type of situation would a higher end consumer grade router be able to fit this bill with DD-WRT on it for tweaking settings, would I be better off looking at a commercial grade router, or what about building a linux machine to act as a router and use a switch in combination with that instead?
I'm looking for the most bang for my buck, since I'm sure that there are plenty of $1000+ commercial routers that could do everything I want but be overkill for my application.
