Can you help me put together a Game Raping desktop?

I have $1,500 to put together a gaming desktop. I want it to have atleast i5 2500k quad unlocked, if not an i7 2600k. Atleast 8-12 gigs of ram, 500G-1TB hard drive space. I also want a 1.5-2 gig video card, isnt 1 gig too small? Oh and Dual video card would be nice. Maybe a 6 core mother board.
