Overclock your CPU. If with one 3870 your cpu was at 70% usage its normal with 6770 Crossfire your cpu usage to be higher.
to be honest i just bought this motherboard too, and i don't know how to set the voltage on bios. i'm not into overclocking, so i don't know much about it. and i was wondering if you could help me to overclock the cpu
