Help with my first gaming PC build(newer post and more simple)

I want a kinda future proof cpmputer that will be able to run newer games at good/decent fps the budget is under $700 so give me some builds so i can look at them

I like Amd CPUs just because they are cheaper and still have great performance,same for their Graphics cards.

Also tell me your opinions on the FX series, i have been cheaking the FX 4300 out.

I have been looking at the Radeon 7870 and it looks great but im not sure if you can fit that in this build.

 

Give me any build i am open to anything, anything $700 or under will be great.

P.S you can also give me builds that are over $700 but try to make it less then $800

This is the build that I would do for the money. I would try to steer clear of the FX 4300 as it is kinda rubbish. The 6300 is my CPU of choice for any budget build in this price range.

If $800 is the absolute limit, I'd go for this build, I have the same CPU, CPU cooler and a similar GTX 660ti, all work great.

Here's a $700 dollar build similar to hiyayhi's build: http://pcpartpicker.com/p/wP0t

If you have $800, than you can consider i5 3570k, a 7950, or a 128 GB SSD.
