Forgive me if I'm wrong... but I think the P5B has a slightly older chipset, but I'll be darned if I can see much of a difference in the board's specs. I own the P5W DH, and overclocking is a breeze. It takes seconds. Keep something in mind, my friend. If you use a large CPU cooler on either of those MB's, you will disrupt airflow to the Northbridge, and will run some high temps, especially if you're OC to the max. Get a Northbridge cooler, or do what I did, install a small case fan blowing right at it. Good Luck!
