Need Help Choosing Gaming PC

[Flexins]

I'm New To Pretty much all gaming PCs, I have looked at three pc's and im trying to stay $550 and below.. All have pretty good specs for gaming from what i've seen. I obviously want a good graphics card but im completely brain dead when it comes to them. All of them have what i need 8GB ram and 500-1tb memory. With atleast 3ghz up. All of them are pre-built and if i were to buy one which would be the best choice and why? Curious and i don't know what other place to ask. Here are the three PCs Im looking for speed and graphics. Please Help! :C Windows 8 Isn't a priority i can live with 7 if the pc is better.

The best will be the first one... but it's still bad, for the price. Rather build one yourself, if you're ok doing it. It's easy.

The first one is an APU CPU coupled with a mGPU which would allow you to play games that isn't demanding, though you could not run next gen games @ 1080p. The other two is a bad case of a GT610 and GT630, both would not get you far.

Building yourself, you would get something like http://pcpartpicker.com/p/1AQ5D though it reach your $550 price range without an OS. Adding an OS would cost another $80. If you feel it goes out of your budget, get the second link and upgrade with a better GPU when you have extra fundings.

Lets Say Building one is out of the question could you link me any good Pre-built pcs under 550 that would run games in good graphics with all the specs i need for a good gaming experience.
