I would get a 3570k.
Then If price isn't a problem I would ge2t the 670.
Then get an asrock z77 pro4 or pro4m depending on if you want atx or matx.
Then get a 40-70 case.
A 1tb hard drive.
8gb ram 1600mhz
and a 600-700 watt psu.
Get the 2gb model of the 670. The 670 is meant to have 2gb and will actually be slower in some cases because it takes longer to read the ram.
