System Build Feedback-memory/os question

[Zangief]

Looking at putting together the following build:
CPU: Intel i7-3770k
MOB:GA-Z77X-UD5H
CPU Cooler: Noctua NH-D14
Memory: 32GB G. Skill Ares Series DDR3-1866
HDD: 256 GB SSD (OS and programs)
250 GB HDD (backup)
1 TB HDD (music/photos/videos)
Video: Asus GeForce GTX 660 (non-ti)
TV Tuner Card: WinTv HVR-1850
DVD burner and BluRay Burner
600w power supply
My old Thermaltake Armor Tower
OS: Win 7 Home
(2) LCD monitors

Main uses will be for photo/video editing and playing WOW

Main questions are regarding Memory. Is 32 Gb too much: A) For the build I'm looking at? B) Because I heard 16Gb is the max for Win 7 Home? I was able to find 1866 for the same price as 1600. May OC in the future but will not be doing any serious tweaking as I have not messed with that before. My current computer is 5-6 years old so I wanted to build something that will last a while.

Any feedback on anything would be appreciated.

yes, unless you are doing serious video editing and rendering, 32gb of RAM is way to much. you will most likely not need over 8.
