I have a DD-WRT firmware on my router, I'm all good there I got 150MB up and download speeds too from FiOS so I'm good there too. The gf and I are heavy gamers, We both have liquid cooled computers and triple screens (I'm down to 2 atm though!). I am however looking for some better home automation and would love a cheap way to turn my TV into a smart TV.
Also, I'll be running Android on mine for the smart tv, the automation will run a linux variant. Google recently announced they will be maintaining a fork of android just for the Pi 3 so I'm quite happy with that. I have been an Android fan since 1.5!
