Cheap gaming build. Budget around $350-$450

Ok, I'm trying to build my first PC to be able to run games like Skyrim, Diablo III, and Final Fantasy 14. I'm trying to do it as cheap as possible.

I know this one is about $20 over budget so I'm wondering if there is anything I could substitute to make it a bit cheaper or would I be better off just spending the little extra.

Which one would you recommend or is there anything better that you know of? If there is anything you would substitute in either build let me know because like I said I'm trying to get it as cheap as possible.

Thanks!
