Need feeback and help with building my first gaming computer

Hello, i am new to this gaming world, and i would really like if someone could help me with what i need for building a computer and which parts is best for my gaming experince. I need it for playing games like Crysis 3, Far Cry, Metro: light, Battle Field 3, Bioshock infinite, and GTA IV.

I live in Denmark but is going to visit my cousin in Netherland and want to build a computer there because it is at least 50 % cheaper. My budget is around 1.000 $

CPU: Intel i5-3570k (http://ark.intel.com/products/65520)
