Building a new gaming pc

[Im new here]

im building a new gaming pc, and i am debating between 2 builds:

1. http://ca.pcpartpicker.com/list/JncVqs
2. http://ca.pcpartpicker.com/list/Jj748K

let me know which is better, or if you have a better one in mind. please keep in mind i am brand new to the whole pc building thing.

Budget: 600 , 650 - 700 CAD if really worth it.

they both have downfalls. in general here are issues i see.

1) ram needs to be purchased in kits. ddr3 is run in dual channel and work best in pairs. a single stick will give you less performance. buying separate sticks is a no-no. they may not work even if they are the same make/model.

2) in one build evga 600b is not a quality psu i would pick for a gaming build, however the s12ii is a good pick in the other build.

3) 5400rpm is not sufficient to hold an operating system in a gaming machine. you want 7200rpm sataIII 32mb-64mb cache.
