Good router for online gaming

[noobrig]

I have 7 computers and 1 PS3 console in my house. For 3 computers (1 wired the rest wireless) and PS3 using wireless for online gaming on a dedicated or busiest/crowded server such as MMORPG, etc, hosting without online player lagging on my server/connection, nat always open, voice & text chat in game such as Mumble, MSN, Ventrilo, Xfire, Steam, Skype, etc, lan party, internet browsing, email, streaming videos/movies HD such as Youtube, etc with 1080p & downloading not all the time or everyday. The other computer are all using wireless for internet browsing, email, streaming videos/movies HD & downloading not all the time or everyday. I want the router has good and strong wireless signal strength that can go through walls, doors, etc without any problems/issues such as lag spikes, connection drops, etc. I don't really care the price and also what's the good USB wireless adapter?
