The black editions are really easy to overclock just go into the bios and find your CPU multiplier and raise it then reboot instant ooverclock. If it starts to become unstable then you will have to raise your vcore voltage a little.
Before overclocking make sure you have the following
1: Good cooling in case
2: Aftermarket heatsink and fan for the CPU
3: Temperature monitioring programs - HwMonitior (www.cpuid.com), or Core temp google it.
4: Quality power supply is needed too but I see you got an ANTEC Signature which is good so you ok there
5: Read your motherboard manual especially the Bios section learn what everything does and where its at if you dont have the manual you can download it at www.gigabyte.com anything you dont understand what it is or does google it.
So until you do all that dont even think about overclocking Good Luck
