Zalman Extreme Vs Cooler Master Aquagate Max

Ok so if i went with the Zalman Extreme it would cost me 70$ for that, now the Cooler Master Aquagate Max is 110$ at Micro Center. Im wondering if that 40$ more for water cooling is worth it. I researched the Zalman Extreme and it was ranked the second coolest AMD heatsink and i am getting a Phenom II x4 955 or 965. Now I was watching the great tj harlow video and he said some cooler came 4 degrees off from his 320$ water cooling. Im wondering if the zalman is gonna be close cause 4 degrees isnt worth 40 to me lol(im cheap) My bedroom is like 50 degrees F(Bedroom in basment) like all the time so i figured Air cooling would do great and be cheaper than water cooling.
