[...] MS7CNB7K7Q THIS ONE! Don't let anyone tell you any different. The 3570k is a WAYYY better processor than that 4 core AMD. And the GTX 660 graphics card is a 220$ card. That's a pretty obvious decision.
BTW I'd build my own machine or have someone build one for me before I'd buy a PC that's already put together. But, to each his own.
