Why go water if you're not going to OC? Hyper 212 Evo works great and saves cash and is whisper quiet (if you want it to be, you can turn it up if you want).
Also don't hate on the GTX 970, I do 60 fps all day long at 1440p (maybe not maxed, but still). 980ti is still to expensive for 20% gain I think. Or get a 980ti but plan on selling it in 2 years and getting a 1080ti+ (I made that up, whatever they will be called in 2 years)
