How do these differ in performance?

How do these differ in performance? I Don't know a whole lot about the details of computers. I Just bought a computer from ibuypower.com and I got the eVGA mobo. Will it run just as good as the others but will just have less features?

edit: Also, what op system is better XP Home Or XP Professional? How are they different?
I chose to get Pro.

really the only difference is features and the bios's could be optimized differently
