CM Hyper 212 Evo with dual fans and real thermal paste (AS5 or better) keeps my CPU on par with H60 V2 / H75 AIO coolers, maybe even H80i strength. Quieter too. AIO's just seem not be worth it unless H100i, CM 240L or better. Nothing like a custom loop though. As for the GTX 780 I have had it for months and got it shortly after it's initial release. It crashed and came back in x8/ mode only. At the time I paid the full $615US for it.
