New $2500 build!

I would really appreciate some help with my new build as I am new to home-brew computers and could use as much help as possible! Thanks!

Approximate Purchase Date: The end of this month, unless you think I should wait for the Haswells.


Budget Range: $2300-$2500+. The plus is, if you think a $50 upgrade would benefit hugely, feel free to add that.


System Usage from Most to Least Important: Gaming, internet browsing, streaming videos.


Are you buying a monitor: Yes, I will need a good monitor.


Do you need to buy OS: Yes, Windows.

Preferred Website(s) for Parts: Whatever's cheapest as long as it isn't "Joe's Cheap Shady Computers."


Location: New York City!


Parts Preferences: Intel CPU, NVIDIA graphics, unless you strongly disagree with that. (Please no AMD/NVIDIA turf wars!)


Overclocking: Maybe, sometime down the line when it gets a little outdated. But again, if you think it a good idea, I will take your advice.


SLI or Crossfire: No, too expensive.


Your Monitor Resolution: 1920x1200, a 24-inch monitor for gaming, so has to have fast refresh rate and low input lag.


Additional Comments: I would like a quiet PC. Again, for hardcore gaming on maxed graphics; it has to be able to handle some of the most lag-inducing games on the market.


Why Are You Upgrading: My current computer sucks. I cannot game on it. Parts are not salvageable as I am giving it to someone.

Thanks for looking at this and maybe helping me with builds,
