Need second opnion on my first build

Approximate Purchase Date: As soon as my bank account is fat enough to buy a rig. Either this week or after two weeks.

Budget Range: 800-1000 (I will probably stick more money into it later.)

System Usage from Most to Least Important: Gaming, School work, Surfing, Maybe a little bit of movies

Do you need to buy OS: Yes

Preferred Website(s) for Parts: Any

Location: ZIP 54011

Parts Preferences: No prefrence just ones that will be reliable.

Overclocking: Maybe

SLI or Crossfire: Yes

Additional Comments: I would rather have power over fancy cases anyday. Also the smaller the case the better because I live in a divorced family so it will be on the move. Although if it is a larger case then so be it. I would like to play Mechwarriors online, Planetside 2, Civ 5 (with friends online, I will probably be hosting it), and more games in the future (this is to replace my consoles that will be soon outdated). So somewhat future proofing would be nice.
