I trust that isn't a sandy bridge i7 as you should be running at 4.7ghz with that voltage!
Further more you don't need that much cooling, sandy bridges are quite cool. Stick to air, water is a needless complication and takes up space in the case.
No no, I have a lousy I7 920

I dont think 1866MHZ ram is going to cut it, seriously consider some 2133MHZ stuff.
He picked an 8 Gb set though, and ram speed makes no difference in video games, only in bandwidth benchmarks.
