Those look like a good deal relative to other RAM on that site. My only concern is those cooling fins on top might cause a problem with the Megahalems. Alot of large coolers sit above some of the ram slots so you should try to check your motherboard and cpu cooler drawings to see if there is room for RAM that tall.
Well as I said, I have a longing for the Classified and Obsidian!
You ask for price help then wont change the two most overpriced things on your list.
