Need advice choosing a new computer.

I'm thinking of getting a new computer for my room. Anywho I'm not all that smart when it comes to stuff like computers so I don't want anyone to say build your own. So where could I get the best high end computer that is future proof? My price range is probably like 1000-2000 bucks. One more thing since my room isn't really close enough to my wireless router where I could run a ethernet cord. How well is a wireless connection for gaming? Like I got a cable isp, but after it run to and from the wireless router I won't have a bad ping or connection will I?
