Best Wireless Router for video-streaming?

Sorry for what is probably a seemingly simple question but I’d like to get a wireless router for my laptop. I do alot of video streaming and might play some highend games on it. I have a Dell Inspiron 1520 with a 1390 wlan mini-card—what would be the highest level router (g, n or n+) that I could use? Any suggestions would be appreiciated.

Thanks!
