First timer: Amd build

[blackcat357]

I am building a computer for a friend. I'm also a 1st time builder and i want to make sure i'm not over looking any thing and that this is a decent working build.
Feel free to make suggestions but nothing Nvidea please I'v had bad experiences with them.

The case and psu have already been purchased.The psu could be returned if needed. Everything is being bought from Amazon btw.

The build:
Amd Fx 8120
Gigabyte GA-990fxa-ud3
coolermaster 212+
Corsair Vengance 8gb (2x4gb) 1600mhz (plan on adding another kit later)
Crucial M4 128gb ssd (with ahci mode enabled)
Western Digital 1TB Caviar Blue sata 3 7200rpm 32mb cache
Cooler master 430 elite case
Asus 24x dvd burner reader
4 120mm blue LED coolermaster fans
Corsair cx600 psu
Windows 7 home premium
Nzxt blue 2 meter LED kit


Sapphire 6870 or XFX 6870 2gb cant decide.

Also need a 120 x 15mm fan for the side but i cant find any.

He wants to have a 3 monitor setup.
The only game he really plays is Warcraft. Sometimes World of Tanks.

I would like to do crossfire. Some sites say the psu can handle it some say it cant. I was kinda planning on adding a 6850.

p.s. NOISE IS NO ISSUE. simply we don't care if it sounds like a freight train

That all should work

Id use a regular 6870 . The extra RAM on the 2 gig model isnt worth it . Theoretically you could crossfire two 6870's on a 600 watt psu but that would depend on how strong the 12 volt rail are
