If your going Ivy Bridge, go with H77 for single video card and no overclocking.
Or go with Z77 for overclocking and dual video cards.
I'm getting an I7 2700k used for 220$. and I play games like planetside and guild wars 2 so I'm pretty sure i need it ahah. I'm going to overclock it too. If i get the 104$ one will my GTX 670 fit on it and a coolermaster evo 212 for cooling the CPU?
