Which CPU/GPU should i get?

Hi i'm looking for a budget build, but the cpu and gpu are really confusing me as i need cheap but also want to play gta iv, minecraft day z, etc.
Should I get something like this http://ca.pcpartpicker.com/parts/partlist/
http://www.futureshop.ca/en-CA/product/asus-asus-m11bb-desktop-pc-amd-a8-6500-1tb-hdd-6gb-ram-windows-8-1-m11bb-ca010s/10284327.aspx?path=c5765ef25813ed642e5687d7f6a05fcfen02
also i went on tomshardware and asked what a good cheap cpu was and someone said a celeron g1620 but i know that celerons are usually ****.
Also would it be beneficial to buy just a AMD A10 5800k as its less than a cpu and gpu and has a Radeon HD 7600D.
Or should i just get this http://www.futureshop.ca/en-CA/product/cyberpowerpc-cyberpowerpc-gamer-ultra-gaming-pc-amd-fx-4130-8gb-ram-500gb-hdd-windows-8-english-gua430/10249910.aspx?path=e3d04fe271fcd220bc32ccfa63d37101en02 as i have to get my computer shop to build the pc as my mom won't allow me to do so, so itll be like 120 more just for that
