Recommend me a great PC rig

$500-700 is considered budget level PC gaming.

No one builds a gaming PC with anything approaching a 10 year life expectancy, even for actual top of the line systems that run in excess of several thousand dollars.

This is very realistically what a $700 budget buys for a build it yourself gaming PC:

As anyone familiar with PC components will recognize (anyone familiar will already have a good idea of what $700 in hardware will buy anyway) this is a competent but modest 1920x1080 gaming PC.

I suggest reading builder articles from Tomshardware.com to better educate yourself on what various budgets will currently buy and the tested performance numbers said builds will yield.
