Unfortunately I'm a pretty big noob when it comes to good value-for-money hardware. Maybe someone can give me tips about what I should or should not do!
I'm currently in need for the following hardware:
CPU: AMD Phenom II X4 955 Black Edition
CPU cooler: Scythe Mugen 2
Motherboard: Gigabyte GA-MA785GMT-UD2H
RAM: GeIL GV34GB1333C7DC (2x 2gb DDR3 CAS 7)
GFX card: Club3D HD 5850 1GB (CGAX-58524IDP)
Harddisk: Samsung Spinpoint F3 HD103SJ, 1TB
The rest of the hardware will be used from my old pc (power 600W, dvd-burner etc.)
Does anyone have any comments on this setup? Also keep in mind I'm a pretty poor student so I can't afford 2 gfx cards etc.

Any help in this matter is really appreciated.
Also, If anyone else needs some help with upgrades of their pc/laptops please feel free to add your request in this topic.
