$700 can get you a more powerful intel based system. You could either get an i5-2400 + h67+ gtx 560 ti, or an i5-2500k+z68+hd6850 if you would like to crossfire or overclock. Personally i would recommend breaking the budget and going for an i5-2500k + z68+ gtx560 ti,but i understand thats not always possible.
