Help With Friends Budget Build

Hey Community,

I am getting a computer built for my friend for games like black ops 2, and he has a budget of 600 dollars. For me that is too hard acheive but trusts me to get him the right specs for games like black ops 2. I am considering building it off ncix.ca because it is the closest to vancouver BC  . I thought coming here would help as the community helped me build my i5 3570k rig which I took the time to build my self. But for this I would like to build it off ncix.ca. Could someone give me all the parts for a 600 dollar rig off the site ncix.ca. Thanks.
