Need help with my new i7 build

What screen size/resolution will you be using?
Here are some Crysis benchmarks for 1920x1200 res.
And you've chosen a PSU before you settled on your video cards. It's usually the other way around.

Spending 4% of your total build budget on a fancy fan controller (especially when you're already spending 10% on a premium case) isn't what I'd call good use of your budget. Are you trying to build a quiet case, or what?
