Well I my main file server run amd 620 and then my everyday workstation run amd 710 with the 4th core unlocked and overclock to 3 ghz. The 620 runs at stock speed because it is just file server/media center box. However I do video converts from .wtv -.dvix about every 3 months. The amd 710 is faster both machines run the same motherboard. To be honest amd 710 box has disadvantage it hard drives are very old 120 gb sata 1 and 80 gb ide from when ever that was latest and greatest. The 620 run all new hard drives that are under 1.5 years old.
