I'm closing in on purchasing a Dell PowerEdge R710 rack server and am curious to know the difference between Dell's power saving bios setting and their performance bios setting. Should I be concerned about choosing the power saving setting? I'll be using this rack for terminal services and definitely want performance when performance is needed. That being said, for the other 3/4's of the day when employees have gone home I'd prefer it if this server wasn't running at 110%.

Thanks in advance.
