Dave,
ont he subject of overclock, modern 3rd serie K cpus are VERY easy to overclock leaving practically everything in "auto" because they are overclocked using TURBO bins, not base multiplier, so you get the best of both world, ultra low power idle and super speed when needed)
a 3770K with water can get to 4.6GHz practically stock(i'm running a 3570K with water at 4.6).
now, depending on the motherboard there's a very cool "trick" setting that essentially enables 4-core full turbo(as you know, intel turbo multis depend on how many cores are active, officially intel has 4/2/2/1 usually that means with 1 core active you get 400Mhz more), that trick setting essentially forces 4/4/4/4 (or whatever your top multi gets set, might be 8, 10, 20, etc) which means you get FULL speed for processor intensive tasks like video encoding
the hyper 212 is THE wonder boy of coolers, it's cheap and works a treat, but you can't beat the thermal inertia of a big water cooler (granted a 2x120mm radiator one).
and a short timelapsed build video with tests would make for a nice altzone vid without running too long.
i'll post screencaps of my bios settings later(i have a msi mainboard but settings are named very similar)
