I'm not familar with your board but you could use a program like SiSoft Sandra,
http://www.sisoftware.demon.co.uk/sandra/ to run tests on your memory and processor, drives, etc. before and after enabling the feature to see if there is a real difference.
Sandra is a really fun program to play around with and it gives you a lot of interesting, usable information about the components of your box. Good Luck!
