Gigabyte G1 Sniper M5 Review Z87 1150 Haswell
We reiterate our opinion that if you're determined to overclock the Core i7-4770K then you really need to invest in a seriously sturdy cooling arrangement. So often in the past people have said to ensure your cooling is great before overclocking, but the 4th Generation CPU demands exceptional cooling.
There is very little between the M5 and GD65 in power draw terms, although it's nice to see that the HD7970 only draws around 60W or so. Proof you don't need a 1KW PSU.
