Don't go with the GA 970A, it doesn't compatible with new Vishera CPU, it's an old motherboard for Zambezi CPU (like FX 8120), you will need to flash BIOS with a Zambezi processor, also check revision of motherboard, a good overclocking motherboard is GA 990XA UD3 new revision or higher, and with ASUS only EVO mobos or higher (like the Sabbertooth)
