*This ASRock (subsidiary of ASUS, kinda) board has a second PCI-e that will allow Crossfire at x8/x8 instead of x16/x4: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
*I'd get 2x4GB for $90 and DDR3 1600 because it's easier to overclock
*HDD: Samsung Spinpoint F3 1TB--look up reviews if you don't believe me.
*Radeon 6950 2GB $260 (unlock to 6970)
*750W Name Brand PSU (Silverstone, Antec, Corsair, XFX--there are some others, you'd want to look for a jonnyguru review of specific models)
*Wireless N Adapter shouldn't cost more than $15 to $20--I love these over ethernet for my desktop
*$16 Newegg DVD burner. Skip the Blu-ray if it's gonna cost you in the graphics department. Buy reader down the line.
*I'd get the 23" LED for $160 @ Tiger Direct: http://www.tigerdirect.com/email/WEM2573.asp?SRCCODE=WE...
*Case: Antec 300 Illusion on Newegg: $70
*CPU Cooler $28: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
This totals about $1200 and I think it's a better build.
