Does it need to have overclocking features? Do you need usb 3.0?
Can I ask why your not going with the newer Ivy Bridge i5/i7?
If it's mainly for gaming, you don't need an i7, you want a i5.
If your not overclocking and using only 1 video card, you can go as low as a H61

for overclocking and usb 3.0

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.
