This is a basic build i put together that is under $600 dollars (this does not include your video card
) So you can already tell ... if you want a "quad core CPU" (This quad core CPU i listed is not even the unlocked i5 for overclocking
) and need an Operating System still.... you are looking at around spending this much.
You can get a cheaper CPU and maybe squeeze in some money for a 650Ti Boost or something (those video cards are like $150 ish) or you can get a cheaper one....
but this list is just to show you what youre looking at..... this isnt an official list im suggesting to you
This is not even including an SSD. An SSD would add another 100 ish to your list...
