new desktop soley for streaming movies/gta 5

So since gta 5 was confirmed for next gen consoles and pc yesterday I figured its time to sell my current laptop and buy a desktop. I never game and dont care about a high end pc, just something good enough to run gta 5 with good fps on at least medium settings.

My current laptop is:

Its from march 2011 so I can likely get $500 or so for it no? What desktop can I get for around $700?

I never move my laptop so a desktop is fine. Also I always watch movies on my ps3 to my tv from my external hooked up into my laptop. Thanks for any suggestions.
