I will buy a new desktop next week. My build is the following:

NZXT Phantom Black
Asus P6X58D-E
i7 950 3.06GHz
Seagate Momentus XT 500Gb
eVGA 570GTX
GSKILL PC3-12800 8gb trident cl7
Corsair gc-800w / NOX Krypton 800w

Any suggestion are highly appreciated if well justified. Also, if my build have any problem please say where it's.
