What CPU and PSU are you going with? That will determine it.

It's kind of pointless to use a 3570K with the H77 as you limit access to the multiplier. Either go with a Z77 motherboard or change your CPU to the i5-3450.

Intel motherboards that start with P or Z support overclocking (example P67, Z77,Z75,Z68) Motherboard chipsets that start with an H or a B do not.

K at the end of Intel CPU model number denotes unlocked multiplier, meaning it can be overclocked.
