Are you going to overclock ? ( if not , the H100 is a big waste )
If you're going to reach for around 4,3-4,5Ghz the H60 will do just fine and you save money .
Also , why the Maximus IV Gene ? I'd drop the H100 , go for the H60 and go for a P8Z68-V pro instead .
8GB of RAM is overkill if he's just going to use it for gaming.
