Need help with a budget gaming pc!

Hello everyone, I'm looking to build a budget gaming pc for around 600$, and i've made these 3 builds, and i can't decide which one is better. Any help regarding the components and which parts to use would be greatly appreciated!

P.S: Sorry for the foreign language on those pictures

The second one, but get a 965, and try and get a 7870, dont get xfx, cooling problems on 7000 series

of course the second one 

 

Id get a 965 though, its worth the extra, so is the 7870, its a workd difference
